### What changes were proposed in this pull request?
Make the ANSI flag part of expressions `Sum` and `Average`'s parameter list, instead of fetching it from the sessional SQLConf.
### Why are the changes needed?
For Views, it is important to show consistent results even the ANSI configuration is different in the running session. This is why many expressions like 'Add'/'Divide' making the ANSI flag part of its case class parameter list.
We should make it consistent for the expressions `Sum` and `Average`
### Does this PR introduce _any_ user-facing change?
Yes, the `Sum` and `Average` inside a View always behaves the same, independent of the ANSI model SQL configuration in the current session.

### What changes were proposed in this pull request?
This PR uses 2 ideas to make `EquivalentExpressions` more efficient:
1. do not keep all the equivalent expressions, we only need a count
2. track the "height" of common subexpressions, to quickly do child-parent sort, and filter out non-child expressions in `addCommonExprs`
This PR also fixes several small bugs (exposed by the refactoring), please see PR comments.

### What changes were proposed in this pull request?
By default, AQE will set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to the spark default parallelism, which is usually quite big. This is to keep the parallelism on par with non-AQE, to avoid perf regressions.
However, this usually leads to many small/empty partitions, and hurts performance (although not worse than non-AQE). Users usually blindly set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to 1, which makes this config quite useless.
This PR adds a new config to set the min partition size, to avoid too small partitions after coalescing. By default, Spark will not respect the target size, and only respect this min partition size, to maximize the parallelism and avoid perf regression in AQE. This PR also adds a bool config to respect the target size when coalescing partitions, and it's recommended to set it to get better overall performance. This PR also deprecates the `COALESCE_PARTITIONS_MIN_PARTITION_NUM` config.
### Why are the changes needed?
AQE is default on now, we should make the perf better in the default case.
### Does this PR introduce _any_ user-facing change?
yes, a new config.

### What changes were proposed in this pull request?
This PR implemented the proposal per [design doc](https://docs.google.com/document/d/1RfFn2e9o_1uHJ8jFGsSakp-BZMizX1uRrJSybMe2a6M) for SPARK-35779.
### Why are the changes needed?
Spark supports dynamic partition filtering that enables reusing parts of the query to skip unnecessary partitions in the larger table during joins. This optimization has proven to be beneficial for star-schema queries which are common in the industry. Unfortunately, dynamic pruning is currently limited to partition pruning during joins and is only supported for built-in v1 sources. As more and more Spark users migrate to Data Source V2, it is important to generalize dynamic filtering and expose it to all v2 connectors.
Please, see the design doc for more information on this effort.
### Does this PR introduce _any_ user-facing change?
Yes, this PR adds a new optional mix-in interface for `Scan` in Data Source V2.
### How was this patch tested?

### What changes were proposed in this pull request?
Add a new configuration `spark.sql.timestampType`, which configures the default timestamp type of Spark SQL, including SQL DDL and Cast clause. Setting the configuration as `TIMESTAMP_NTZ` will use `TIMESTAMP WITHOUT TIME ZONE` as the default type while putting it as `TIMESTAMP_LTZ` will use `TIMESTAMP WITH LOCAL TIME ZONE`.
The default value of the new configuration is TIMESTAMP_LTZ, which is consistent with previous Spark releases.

unionByName does not supports struct having same col names but different sequence
```
val df1 = Seq((1, Struct1(1, 2))).toDF("a", "b")
val df2 = Seq((1, Struct2(1, 2))).toDF("a", "b")
val unionDF = df1.unionByName(df2)
```
it gives the exception
`org.apache.spark.sql.AnalysisException: Union can only be performed on tables with the compatible column types. struct<c2:int,c1:int> <> struct<c1:int,c2:int> at the second column of the second table; 'Union false, false :- LocalRelation [_1#38, _2#39] +- LocalRelation _1#45, _2#46`
In this case the col names are same so this unionByName should have the support to check within in the Struct if col names are same it should not throw this exception and works.
after fix we are getting the result
```
val unionDF = df1.unionByName(df2)

### What changes were proposed in this pull request?
If the user creates a view in 2.4 and reads it in 3.1/3.2, there will be an incompatible schema issue.
So this PR adds a view ddl in the error message to prompt the user recreating the view to fix the
incompatible issue.
For example:
```sql
-- create view in 2.4
CREATE TABLE IF NOT EXISTS t USING parquet AS SELECT '1' as a, '20210420' as b"
CREATE OR REPLACE VIEW v AS SELECT CAST(t.a AS INT), to_date(t.b, 'yyyyMMdd') FROM t
-- select view in master
SELECT * FROM v
```
Then we will get below error:
```
cannot resolve '`to_date(spark_catalog.default.t.b, 'yyyyMMdd')`' given input columns: [a, to_date(b, yyyyMMdd)];
```

2. As we have the function to_timestamp_ntz, this makes the names consistent.
3. We will introduce a new SQL configuration `spark.sql.timestampType` for the default timestamp type. The configuration values can be "TIMESTMAP_NTZ" or "TIMESTMAP_LTZ" for simplicity.

### What changes were proposed in this pull request?
* Add a new rule `ExpandShufflePartitions` in AQE `queryStageOptimizerRules`
* Add a new config `spark.sql.adaptive.optimizeSkewsInRebalancePartitions.enabled` to decide if should enable the new rule
The new rule `OptimizeSkewInRebalancePartitions` only handle two shuffle origin `REBALANCE_PARTITIONS_BY_NONE` and `REBALANCE_PARTITIONS_BY_COL` for data skew issue. And re-use the exists config `ADVISORY_PARTITION_SIZE_IN_BYTES` to decide what partition size should be.
### Why are the changes needed?
Currently, we don't support expand partition dynamically in AQE which is not friendly for some data skew job.
Let's say if we have a simple query:
```
SELECT /*+ REBALANCE(col) */ * FROM table
```
The column of `col` is skewed, then some shuffle partitions would handle too much data than others.
If we haven't inroduced extra shuffle, we can optimize this case by expanding partitions in AQE.

### What changes were proposed in this pull request?
Add a new ANSI type coercion rule: when getting a date field from a Timestamp column, cast the column as Date type.
This is Spark's current hack to make the implementation simple. In the default type coercion rules, the implicit cast rule does the work. However, The ANSI implicit cast rule doesn't allow converting Timestamp type as Date type, so we need to have this additional rule to make sure the date field extraction from Timestamp columns works.

This patch refactors the evaluation of subexpressions.
There are two changes:
1. Clean up subexpression code after evaluation to avoid duplicate evaluation.
2. Evaluate all children subexpressions when evaluating a subexpression.
### Why are the changes needed?
Currently `subexpressionEliminationForWholeStageCodegen` return the gen-ed code of subexpressions. The caller simply puts the code into its code block. We need more flexible evaluation here. For example, for Filter operator's subexpression evaluation, we may need to evaluate particular subexpression for one predicate. Current approach cannot satisfy the requirement.

Replace the type collection `AllTimestampTypes` with the new data type `AnyTimestampType`
### Why are the changes needed?
As discussed in https://github.com/apache/spark/pull/33115#discussion_r659866760, it is more convenient to have a new data type "AnyTimestampType" instead of using type collection `AllTimestampTypes`:
1. simplify the pattern match
2. In the default type coercion rules, when implicit casting a type to a TypeCollection type, Spark chooses the first convertible data type as the result. If we are going to make the default timestamp type configurable, having AnyTimestampType is better

This issue happens when aliases are eliminated by `AliasHelper.replaceAliasButKeepName` or `AliasHelper.trimNonTopLevelAliases` called via analyzer/optimizer

I investigated functions which can be affected this issue but I found only `arrays_zip` so far.
To fix this issue, this PR changes the definition of `ArraysZip` to retain field names to avoid being re-written by analyzer/optimizer.
### Why are the changes needed?
This is apparently a bug.
### Does this PR introduce _any_ user-facing change?
No. After this change, the field names are no longer re-written but it should be expected behavior for users.
### How was this patch tested?
New tests.

### What changes were proposed in this pull request?
This PR changes the unionByName with null filling logic to append new nested struct fields from the right side of the union to the schema versus sorting fields alphabetically. It removes the need to use UpdateField expressions, and just directly projects new nested structs from each side of the union with the correct schema. This changes the union'd schema from being alphabetically sorted previously to now "left dominant", where the fields from the left side of the union are included and then the missing ones from the right are added in the same order found originally.
### Why are the changes needed?
Certain nested structs would cause unionByName with null filling to error out due to part of the logic for rewriting the expression tree to sort the structs.
### Does this PR introduce _any_ user-facing change?
Yes, nested struct fields will be in a different order after unionByName with null filling than before, though shouldn't cause much effective difference.
### How was this patch tested?
Updated existing tests based on the new StructField ordering and added a new test for the case that was broken originally.

* Add a new repartition operator `RebalanceRepartition`.
* Support a new hint `REBALANCE`
After this patch, user can run this query:
```sql
SELECT /*+ REBALANCE(c) */ * FROM t
```
### Why are the changes needed?
Add a new hint to distingush if we can optimize it safely.
This new hint can let AQE optimize with `CustomShuffleReaderExec` safely. Currently, AQE can only coalesce shuffle partitions but can not expand shuffle partitions due to the semantics of output partitioning.
Let's say we have a query:
```sql
SELECT /*+ REPARTITION(col) */ * FROM t
```
AQE can not expand the shuffle partitions even if `col` is skewed because expanding shuffle partitions will break the hashed output paritioning of `RepartitionByExpression`. But if the query is use`REPARTITION_BY_AQE`, AQE can optimize it without considering the semantics of output partitioning.

Yes, a new hint.

… sum of the digits is greater than 38
### What changes were proposed in this pull request?
Since Spark 3.1.1, NULL is returned when casting a string with many decimal places to a decimal type. If the sum of the digits before and after the decimal point is less than 39, a value is returned. From 39 digits, however, NULL is returned.
This worked until Spark 3.0.X.
Code to reproduce:
A string with 2 decimal places in front of the decimal point and 37 decimal places after the decimal point returns null
```
val data = Seq(
"28.9259999999999983799625624669715762138",
"28.925999999999998379962562466971576213",
"2.9259999999999983799625624669715762138"
)
val df = data.toDF("num")
df.withColumn("numConverted", col("num").cast("decimal(38, 5)")).show()
```
before this pull request, the result is
+----------------------+---------------+
| num |numConverted|
+----------------------+---------------+
|28.92599999999999...| null|

|2.925999999999998...| 2.92600|

The analyzer will turn a `dataset.withColumn("colName", expressionWithWindowFunction)` method call to a `Project - Window - Project` chain in the logical plan. When this method is called multiple times in a row, then the projects can block the `Window` nodes from being transposed by the current `TransposeWindow` rule.

### What changes were proposed in this pull request?
The current OuterReference resolution is a bit weird: when the outer plan has more than one child, it resolves OuterReference from the output of each child, one by one, left to right.
This is incorrect in the case of join, as the column name can be ambiguous if both left and right sides output this column.
This PR fixes this bug by resolving OuterReference with `outerPlan.resolveChildren`, instead of something like `outerPlan.children.foreach(_.resolve(...))`
### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?
The problem only occurs in join, and join condition doesn't support correlated subquery yet. So this PR only improves the error message. Before this PR, people see

This PR fixes an issue that `IntervalUtils.toDayTimeIntervalString` doesn't consider the case that a day-time interval type is casted as another day-time interval type.
if data of `interval day to second` is casted as `interval hour to second`, the value of the day is multiplied by 24 and added to the value of hour. For example, `INTERVAL '1 2' DAY TO HOUR` will be `INTERVAL '26' HOUR` if it's casted.
If this behavior is intended, it should be stringified as `INTERVAL '26' HOUR` but currently, it will be `INTERVAL '2' HOUR`

### What changes were proposed in this pull request?
When SQL function `to_timestamp_ntz` has invalid format pattern input, throw a runtime exception with hints for the valid patterns, instead of throwing an upgrade exception with suggestions to use legacy formatters.
### Why are the changes needed?
As discussed in https://github.com/apache/spark/pull/32995/files#r655148980, there is an error message saying
"You may get a different result due to the upgrading of Spark 3.0: Fail to recognize 'yyyy-MM-dd GGGGG' pattern in the DateTimeFormatter. 1) You can set spark.sql.legacy.timeParserPolicy to LEGACY to restore the behavior before Spark 3.0"
This is not true for function to_timestamp_ntz, which only uses the Iso8601TimestampFormatter and added since Spark 3.2. We should improve it.
### Does this PR introduce _any_ user-facing change?
No, the new SQL function is not released yet.

### What changes were proposed in this pull request?
Implement new SQL function: `to_timestamp_ntz`.
The syntax is similar to the built-in function `to_timestamp`:
```
to_timestamp_ntz ( <date_expr> )
to_timestamp_ntz ( <timestamp_expr> )
to_timestamp_ntz ( <string_expr> [ , <format> ] )
```
The naming is from snowflake: https://docs.snowflake.com/en/sql-reference/functions/to_timestamp.html
### Why are the changes needed?
Adds a new SQL function to create a literal/column of timestamp without time zone.
It's convenient for both end-users and developers.

### What changes were proposed in this pull request?
Extend the `CollapseWindow` rule to collapse `Window` nodes, that have `Project` between them.
### Why are the changes needed?
The analyzer will turn a `dataset.withColumn("colName", expressionWithWindowFunction)` method call to a `Project - Window - Project` chain in the logical plan. When this method is called multiple times in a row, then the projects can block the `Window` nodes from being collapsed by the current `CollapseWindow` rule.

### What changes were proposed in this pull request?
This PR fixes error message shown when changing a column type to year-month/day-time interval type is attempted.
### Why are the changes needed?
It's for consistent behavior.
Updating column types to interval types are prohibited for V2 source tables.
So, if we attempt to update the type of a column to the conventional interval type, an error message like `Error in query: Cannot update <table> field <column> to interval type;`.
But, for year-month/day-time interval types, another error message like `Error in query: Cannot update <table> field <column>:<type> cannot be cast to interval year;`.
You can reproduce with the following procedure.
```
$ bin/spark-sql
spark-sql> SET spark.sql.catalog.mycatalog=<a catalog implementation class>;
spark-sql> CREATE TABLE mycatalog.t1(c1 int) USING <V2 datasource implementation class>;
spark-sql> ALTER TABLE mycatalog.t1 ALTER COLUMN c1 TYPE interval year to month;
```

### What changes were proposed in this pull request?
This PR fixes an issue that `IntervalUtils.toYearMonthIntervalString` doesn't consider the case that year-month interval type is casted as month interval type.
If a year-month interval data is casted as month interval, the value of the year is multiplied by `12` and added to the value of month. For example, `INTERVAL '1-2' YEAR TO MONTH` will be `INTERVAL '14' MONTH` if it's casted.
If this behavior is intended, it's stringified to be `'INTERVAL 14' MONTH` but currently, it will be `INTERVAL '2' MONTH`
### Why are the changes needed?
It's a bug if the behavior of cast is intended.
### Does this PR introduce _any_ user-facing change?
No, because this feature is not released yet.

### What changes were proposed in this pull request?
This patch proposes to add an internal config for ignoring metadata of `FileStreamSink` when reading the output path.
### Why are the changes needed?
`FileStreamSink` produces a metadata directory which logs output files per micro-batch. When we read from the output path, Spark will look at the metadata and ignore other files not in the log.
Normally it works well. But for some use-cases, we may need to ignore the metadata when reading the output path. For example, when we change the streaming query and must to run it with new checkpoint directory, we cannot use previous metadata. If we create a new metadata too, when we read the output path later in Spark, Spark only reads the files listed in the new metadata. The files written before we use new checkpoint and metadata are ignored by Spark.
Although seems we can output to different output directory every time, but it is bad idea as we will produce many directories unnecessarily.
We need a config for ignoring the metadata of `FileStreamSink` when reading the output path.

### What changes were proposed in this pull request?
Currently, `ResolveAggregateFunctions` is a complicated rule that recursively calls the entire analyzer to resolve aggregate functions in parent nodes of aggregate. It's kind of necessary as we need to do many things to identify the aggregate function and push it down to the aggregate node: resolve columns as if they are in the aggregate node, resolve functions, apply type coercion, etc. However, this is overly complicated and it's hard to fully understand how the resolution is done there. It also leads to hacks such as the [char/varchar hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2396-L2401), [subquery hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2274-L2277), [grouping function hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2465-L2467), etc.
This PR simplifies the `ResolveAggregateFunctions` rule and clarifies the resolution logic. To resolve aggregate functions/grouping columns in HAVING, ORDER BY and `df.where`, we expand the aggregate node below to output these required aggregate functions/grouping columns. In details, when resolving an expression from the parent of an aggregate node:
1. try to resolve columns with `agg.child` and wrap the result with `TempResolvedColumn`.
2. try to resolve subqueries with `agg.child`
3. if the expression is not resolved, return it and wait for other rules to resolve it, such as resolve functions, type coercions, etc.
4. if the expression is resolved, we transform it and push aggregate functions/grouping columns into the aggregate node below.
4.1 the expression may already present in `agg.aggregateExpressions`, we can simply replace the expression with attr ref.
4.2 if a `TempResolvedColumn` is neither inside an aggregate function, or wrap a grouping column, turn it back to an `UnresolvedAttribute`
5. after the main resolution batch, remove all `TempResolvedColumn` and turn them back to `UnresolvedAttribute`.

### What changes were proposed in this pull request?
This PR add a feature which parse day-time interval literals to tightest type.
### Why are the changes needed?
To comply with the ANSI behavior.
For example, `INTERVAL '10 20:30' DAY TO MINUTE` should be parsed as `DayTimeIntervalType(DAY, MINUTE)` but not as `DayTimeIntervalType(DAY, SECOND)`.
### Does this PR introduce _any_ user-facing change?
No because `DayTimeIntervalType` will be introduced in `3.2.0`.

Using copy-on-write for `SQLConf.sqlConfEntries` and `SQLConf.staticConfKeys` to reduce contention in concurrent workloads.
### Why are the changes needed?
The global locks used to protect `SQLConf.sqlConfEntries` map and the `SQLConf.staticConfKeys` set can cause significant contention on the `SQLConf` instance in a concurrent setting.
Using copy-on-write versions should reduce the contention given that modifications to the configs are relatively rare.

### What changes were proposed in this pull request?
Extend DayTimeIntervalType to support interval fields. Valid interval field values:
- 0 (DAY)
- 1 (HOUR)
- 2 (MINUTE)
- 3 (SECOND)
After the changes, the following day-time interval types are supported:
1. `DayTimeIntervalType(0, 0)` or `DayTimeIntervalType(DAY, DAY)`
2. `DayTimeIntervalType(0, 1)` or `DayTimeIntervalType(DAY, HOUR)`
3. `DayTimeIntervalType(0, 2)` or `DayTimeIntervalType(DAY, MINUTE)`
4. `DayTimeIntervalType(0, 3)` or `DayTimeIntervalType(DAY, SECOND)`. **It is the default one**. The second fraction precision is microseconds.
5. `DayTimeIntervalType(1, 1)` or `DayTimeIntervalType(HOUR, HOUR)`
6. `DayTimeIntervalType(1, 2)` or `DayTimeIntervalType(HOUR, MINUTE)`
7. `DayTimeIntervalType(1, 3)` or `DayTimeIntervalType(HOUR, SECOND)`
8. `DayTimeIntervalType(2, 2)` or `DayTimeIntervalType(MINUTE, MINUTE)`
9. `DayTimeIntervalType(2, 3)` or `DayTimeIntervalType(MINUTE, SECOND)`
10. `DayTimeIntervalType(3, 3)` or `DayTimeIntervalType(SECOND, SECOND)`
### Why are the changes needed?
In the current implementation, Spark supports only `interval day to second` but the SQL standard allows to specify the start and end fields. The changes will allow to follow ANSI SQL standard more precisely.
### Does this PR introduce _any_ user-facing change?
Yes but `DayTimeIntervalType` has not been released yet.

// Unfolded Math.floorMod(us, MICROS_PER_SECOND) to reuse the result of

But the overflow is acceptable because it won't produce any change to the result
However, when convert the instant back to micro value, it will raise Overflow Error
```

### What changes were proposed in this pull request?
This PR adds support for lateral subqueries. A lateral subquery is a subquery preceded by the `LATERAL` keyword in the FROM clause of a query that can reference columns in the preceding FROM items. For example:
```sql
SELECT * FROM t1, LATERAL (SELECT * FROM t2 WHERE t1.a = t2.c)
```
A new subquery expression`LateralSubquery` is used to represent a lateral subquery. It is similar to `ScalarSubquery` but can return multiple rows and columns. A new logical unary node `LateralJoin` is used to represent a lateral join.
Here is the analyzed plan for the above query:
```scala
Project [a, b, c, d]
+- LateralJoin lateral-subquery [a], Inner
: +- Project [c, d]
: +- Filter (outer(a) = c)
: +- Relation [c, d]
+- Relation [a, b]
```
Similar to a correlated subquery, a lateral subquery can be viewed as a dependent (nested loop) join where the evaluation of the right subtree depends on the current value of the left subtree. The same technique to decorrelate a subquery is used to decorrelate a lateral join:
```scala
Project [a, b, c, d]
+- LateralJoin lateral-subquery [a && a = c], Inner // pull up correlated predicates as join conditions
: +- Project [c, d]
: +- Relation [c, d]
+- Relation [a, b]
```
Then the lateral join can be rewritten into a normal join:
```scala
Join Inner (a = c)
:- Relation [a, b]
+- Relation [c, d]
```
#### Follow-ups:
1. Similar to rewriting correlated scalar subqueries, rewriting lateral joins is also subject to the COUNT bug (See SPARK-15370 for more details). This is **not** handled in the current PR as it requires a sizeable amount of refactoring. It will be addressed in a subsequent PR (SPARK-35551).
2. Currently Spark does use outer query references to resolve star expressions in subqueries. This is not lateral subquery specific and can be handled in a separate PR (SPARK-35618)
### Why are the changes needed?
To support an ANSI SQL feature.
### Does this PR introduce _any_ user-facing change?
Yes. It allows users to use lateral subqueries in the FROM clause of a query.
### How was this patch tested?
- Parser test: `PlanParserSuite.scala`
- Analyzer test: `ResolveSubquerySuite.scala`
- Optimizer test: `PullupCorrelatedPredicatesSuite.scala`
- SQL test: `join-lateral.sql`, `postgreSQL/join.sql`

### What changes were proposed in this pull request?
In the PR, I propose to extend Spark SQL API to accept `java.time.LocalDateTime` as an external type of recently added new Catalyst type - `TimestampWithoutTZ`. The Java class `java.time.LocalDateTime` has a similar semantic to ANSI SQL timestamp without timezone type, and it is the most suitable to be an external type for `TimestampWithoutTZType`. In more details:
* Added `TimestampWithoutTZConverter` which converts java.time.LocalDateTime instances to/from internal representation of the Catalyst type `TimestampWithoutTZType` (to Long type). The `TimestampWithoutTZConverter` object uses new methods of DateTimeUtils:
* localDateTimeToMicros() converts the input date time to the total length in microseconds.
* microsToLocalDateTime() obtains a java.time.LocalDateTime
* Support new type `TimestampWithoutTZType` in RowEncoder via the methods createDeserializerForLocalDateTime() and createSerializerForLocalDateTime().
* Extended the Literal API to construct literals from `java.time.LocalDateTime` instances.
### Why are the changes needed?
To allow users parallelization of `java.time.LocalDateTime` collections, and construct timestamp without time zone columns. Also to collect such columns back to the driver side.
### Does this PR introduce _any_ user-facing change?
The PR extends existing functionality. So, users can parallelize instances of the java.time.LocalDateTime class and collect them back.
```
scala> val ds = Seq(java.time.LocalDateTime.parse("1970-01-01T00:00:00")).toDS
ds: org.apache.spark.sql.Dataset[java.time.LocalDateTime] = [value: timestampwithouttz]

### What changes were proposed in this pull request?
This patch introduces a new option to specify the minimum number of offsets to read per trigger i.e. minOffsetsPerTrigger and maxTriggerDelay to avoid the infinite wait for the trigger.
This new option will allow skipping trigger/batch when the number of records available in Kafka is low. This is a very useful feature in cases where we have a sudden burst of data at certain intervals in a day and data volume is low for the rest of the day.
'maxTriggerDelay' option will help to avoid cases of infinite delay in scheduling trigger and the trigger will happen irrespective of records available if the maxTriggerDelay time exceeds the last trigger. It would be an optional parameter with a default value of 15 mins. This option will be only applicable if minOffsetsPerTrigger is set.
minOffsetsPerTrigger option would be optional of course, but once specified it would take precedence over maxOffestsPerTrigger which will be honored only after minOffsetsPerTrigger is satisfied.
### Why are the changes needed?
There are many scenarios where there is a sudden burst of data at certain intervals in a day and data volume is low for the rest of the day. Tunning such jobs is difficult as decreasing trigger processing time increasing the number of batches and hence cluster resource usage and adds to small file issues. Increasing trigger processing time adds consumer lag. This patch tries to address this issue.
### How was this patch tested?
This patch was tested by adding test cases as well as manually on a cluster where the job was running for a full one day with a data burst happening once a day.
Here is the picture of databurst and hence consumer lag:

This is how the job behaved at burst time running every 4.5 mins (which is the specified trigger time):
<img width="1154" alt="Burst Time" src="https://user-images.githubusercontent.com/1044003/116997919-12f8dc00-acfb-11eb-9b0a-98387fc67560.png">
This is job behavior during the non-burst time where it is skipping 2 to 3 triggers and running once every 9 to 13.5 mins

### What changes were proposed in this pull request?
Extend Catalyst's type system by a new type that conforms to the SQL standard (see SQL:2016, section 4.6.2): TimestampWithoutTZType represents the timestamp without time zone type
### Why are the changes needed?
Spark SQL today supports the TIMESTAMP data type. However the semantics provided actually match TIMESTAMP WITH LOCAL TIMEZONE as defined by Oracle. Timestamps embedded in a SQL query or passed through JDBC are presumed to be in session local timezone and cast to UTC before being processed.
These are desirable semantics in many cases, such as when dealing with calendars.
In many (more) other cases, such as when dealing with log files it is desirable that the provided timestamps not be altered.
SQL users expect that they can model either behavior and do so by using TIMESTAMP WITHOUT TIME ZONE for time zone insensitive data and TIMESTAMP WITH LOCAL TIME ZONE for time zone sensitive data.
Most traditional RDBMS map TIMESTAMP to TIMESTAMP WITHOUT TIME ZONE and will be surprised to see TIMESTAMP WITH LOCAL TIME ZONE, a feature that does not exist in the standard.
In this new feature, we will introduce TIMESTAMP WITH LOCAL TIMEZONE to describe the existing timestamp type and add TIMESTAMP WITHOUT TIME ZONE for standard semantic.
Using these two types will provide clarity.
This is a starting PR. See more details in https://issues.apache.org/jira/browse/SPARK-35662

### What changes were proposed in this pull request?
Optimizes the retrieval of approximate quantiles for an array of percentiles.
* Adds an overload for QuantileSummaries.query that accepts an array of percentiles and optimizes the computation to do a single pass over the sketch and avoid redundant computation.
* Modifies the ApproximatePercentiles operator to call into the new method.
All formatting changes are the result of running ./dev/scalafmt
### Why are the changes needed?
The existing implementation does repeated calls per input percentile resulting in redundant computation.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Added unit tests for the new method.

### What changes were proposed in this pull request?
A followup for 345d35ed1a, in this PR we support CURRENT_USER without tailing parentheses in default mode. And for ANSI mode, we can only use CURRENT_USER without tailing parentheses because it is a reserved keyword that cannot be used as a function name
### Why are the changes needed?

### What changes were proposed in this pull request?
Sets `references` for `NamedLambdaVariable` and `LambdaFunction`.
| Expression | NamedLambdaVariable | LambdaFunction |
| --- | --- | --- |
| References before | None | All function references |
| References after | self.toAttribute | Function references minus arguments' references |
In `NestedColumnAliasing`, this means that `ExtractValue(ExtractValue(attr, lv: NamedLambdaVariable), ...)` now references both `attr` and `lv`, rather than just `attr`. As a result, it will not be included in the nested column references.
### Why are the changes needed?

### What changes were proposed in this pull request?
Currently, we do not have a suitable definition of the `user` concept in Spark. We only have a `sparkUser` app widely but do not support identify or retrieve the user information from a session in STS or a runtime query execution.
`current_user()` is very popular and supported by plenty of other modern or old school databases, and also ANSI compliant.
This PR add `current_user()` as a SQL function. And, they are the same. In this PR, we add these functions w/o ambiguity.
1. For a normal single-threaded Spark application, clearly the `sparkUser` is always equivalent to `current_user()` .
2. For a multi-threaded Spark application, e.g. Spark thrift server, we use a `ThreadLocal` variable to store the client-side user(after authenticated) before running the query and retrieve it in the parser.
### Why are the changes needed?

### What changes were proposed in this pull request?
In the PR, I propose to support special datetime values introduced by #25708 and by #25716 only in typed literals, and don't recognize them in parsing strings to dates/timestamps. The following string values are supported only in typed timestamp literals:
- `epoch [zoneId]` - `1970-01-01 00:00:00+00 (Unix system time zero)`
- `today [zoneId]` - midnight today.
- `yesterday [zoneId]` - midnight yesterday
- `tomorrow [zoneId]` - midnight tomorrow
- `now` - current query start time.
For example:
```sql
spark-sql> SELECT timestamp 'tomorrow';
2019-09-07 00:00:00
```
Similarly, the following special date values are supported only in typed date literals:
- `epoch [zoneId]` - `1970-01-01`
- `today [zoneId]` - the current date in the time zone specified by `spark.sql.session.timeZone`.
- `yesterday [zoneId]` - the current date -1
- `tomorrow [zoneId]` - the current date + 1
- `now` - the date of running the current query. It has the same notion as `today`.
For example:
```sql
spark-sql> SELECT date 'tomorrow' - date 'yesterday';
2
```
### Why are the changes needed?
In the current implementation, Spark supports the special date/timestamp value in any input strings casted to dates/timestamps that leads to the following problems:
- If executors have different system time, the result is inconsistent, and random. Column values depend on where the conversions were performed.
- The special values play the role of distributed non-deterministic functions though users might think of the values as constants.
### Does this PR introduce _any_ user-facing change?
Yes but the probability should be small.
### How was this patch tested?
By running existing test suites:
```
$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite -- -z interval.sql"
$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite -- -z date.sql"

This PR adds a unit test to show a bug in the latest janino version which fails to compile valid Java code. Unfortunately, I can't share the exact query that can trigger this bug (includes some custom expressions), but this pattern is not very uncommon and I believe can be triggered by some real queries.
A follow-up is needed before the 3.2 release, to either fix this bug in janino, or revert the janino version upgrade, or work around it in Spark.

### What changes were proposed in this pull request?
This PR refactors `SubqueryExpression` class. It removes the children field from SubqueryExpression's constructor and adds `outerAttrs` and `joinCond`.
### Why are the changes needed?
Currently, the children field of a subquery expression is used to store both collected outer references in the subquery plan and join conditions after correlated predicates are pulled up.
For example:
`SELECT (SELECT max(c1) FROM t1 WHERE t1.c1 = t2.c1) FROM t2`
During the analysis phase, outer references in the subquery are stored in the children field: `scalar-subquery [t2.c1]`, but after the optimizer rule `PullupCorrelatedPredicates`, the children field will be used to store the join conditions, which contain both the inner and the outer references: `scalar-subquery [t1.c1 = t2.c1]`. This is why the references of SubqueryExpression excludes the inner plan's output:
29ed1a2de4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/subquery.scala (L68-L69)
This can be confusing and error-prone. The references for a subquery expression should always be defined as outer attribute references.

The main code change is:
* Change rule `DemoteBroadcastHashJoin` to `DynamicJoinSelection` and add shuffle hash join selection code.
* Specify a join strategy hint `SHUFFLE_HASH` if AQE think a join can be converted to SHJ.
* Skip `preferSortMerge` config check in AQE side if a join can be converted to SHJ.
### Why are the changes needed?
Use AQE runtime statistics to decide if we can use shuffled hash join instead of sort merge join. Currently, the formula of shuffled hash join selection dose not work due to the dymanic shuffle partition number.

### What changes were proposed in this pull request?
This PR fixes a bug with subexpression elimination for CaseWhen statements. https://github.com/apache/spark/pull/30245 added support for creating subexpressions that are present in all branches of conditional statements. However, for a statement to be in "all branches" of a CaseWhen statement, it must also be in the elseValue.
### Why are the changes needed?
Fix a bug where a subexpression can be created and run for branches of a conditional that don't pass. This can cause issues especially with a UDF in a branch that gets executed assuming the condition is true.
### Does this PR introduce _any_ user-facing change?
Yes, fixes a potential bug where a UDF could be eagerly executed even though it might expect to have already passed some form of validation. For example:
```
val col = when($"id" < 0, myUdf($"id"))
spark.range(1).select(when(col > 0, col)).show()
```
`myUdf($"id")` is considered a subexpression and eagerly evaluated, because it is pulled out as a common expression from both executions of the when clause, but if `id >= 0` it should never actually be run.
### How was this patch tested?
Updated existing test with new case.

### What changes were proposed in this pull request?
This patch fixes a bug when dealing with common expressions in conditional expressions such as `CaseWhen` during subexpression elimination.
For example, previously we find common expressions among conditions of `CaseWhen`, but children expressions are also counted into. We should not count these children expressions as common expressions.
### Why are the changes needed?
If the redundant children expressions are counted as common expressions too, they will be redundantly evaluated and miss the subexpression elimination opportunity.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Added tests.

### What changes were proposed in this pull request?
This PR proposes to avoid wrapping if-else to the constant literals for `percentage` and `accuracy` in `percentile_approx`. They are expected to be literals (or foldable expressions).
Pivot works by two phrase aggregations, and it works with manipulating the input to `null` for non-matched values (pivot column and value).
Note that pivot supports an optimized version without such logic with changing input to `null` for some types (non-nested types basically). So the issue fixed by this PR is only for complex types.
```scala
val df = Seq(
("a", -1.0), ("a", 5.5), ("a", 2.5), ("b", 3.0), ("b", 5.2)).toDF("type", "value")
.groupBy().pivot("type", Seq("a", "b")).agg(
percentile_approx(col("value"), array(lit(0.5)), lit(10000)))
df.show()
```
**Before:**
```
org.apache.spark.sql.AnalysisException: cannot resolve 'percentile_approx((IF((type <=> CAST('a' AS STRING)), value, CAST(NULL AS DOUBLE))), (IF((type <=> CAST('a' AS STRING)), array(0.5D), NULL)), (IF((type <=> CAST('a' AS STRING)), 10000, CAST(NULL AS INT))))' due to data type mismatch: The accuracy or percentage provided must be a constant literal;

### What changes were proposed in this pull request?
This patch sorts equivalent expressions based on their child-parent relation.
### Why are the changes needed?
`EquivalentExpressions` maintains a map of equivalent expressions. It is `HashMap` now so the insertion order is not guaranteed to be preserved later. Subexpression elimination relies on retrieving subexpressions from the map. If there is child-parent relationships among the subexpressions, we want the child expressions come first than parent expressions, so we can replace child expressions in parent expressions with subexpression evaluation.
For example, we have two different expressions `Add(Literal(1), Literal(2))` and `Add(Literal(3), add)`.
Case 1: child subexpr comes first.
```scala
addExprTree(add)
addExprTree(Add(Literal(3), add))
addExprTree(Add(Literal(3), add))
```
Case 2: parent subexpr comes first. For this case, we need to sort equivalent expressions.
```
addExprTree(Add(Literal(3), add)) => We add `Add(Literal(3), add)` into the map first, then add `add` into the map
addExprTree(add)
addExprTree(Add(Literal(3), add))
```
As we are going to sort equivalent expressions at all, we don't need `LinkedHashMap` but just do sorting.

This PR proposes to format strings correctly for `PushedFilters`. For example, `explain()` for a query below prints `v in (array('a'))` as `PushedFilters: [In(v, [WrappedArray(a)])]`;
```

### What changes were proposed in this pull request?
CTAS with location clause acts as an insert overwrite. This can cause problems when there are subdirectories within a location directory.
This causes some users to accidentally wipe out directories with very important data. We should not allow CTAS with location to a non-empty directory.
### Why are the changes needed?
Hive already handled this scenario: HIVE-11319
Steps to reproduce:
```scala
sql("""create external table `demo_CTAS`( `comment` string) PARTITIONED BY (`col1` string, `col2` string) STORED AS parquet location '/tmp/u1/demo_CTAS'""")
sql("""INSERT OVERWRITE TABLE demo_CTAS partition (col1='1',col2='1') VALUES ('abc')""")
sql("select* from demo_CTAS").show
sql("""create table ctas1 location '/tmp/u2/ctas1' as select * from demo_CTAS""")
sql("select* from ctas1").show
sql("""create table ctas2 location '/tmp/u2' as select * from demo_CTAS""")
```
Before the fix: Both create table operations will succeed. But values in table ctas1 will be replaced by ctas2 accidentally.
After the fix: `create table ctas2...` will throw `AnalysisException`:
```
org.apache.spark.sql.AnalysisException: CREATE-TABLE-AS-SELECT cannot create table with location to a non-empty directory /tmp/u2 . To allow overwriting the existing non-empty directory, set 'spark.sql.legacy.allowNonEmptyLocationInCTAS' to true.
```
### Does this PR introduce _any_ user-facing change?
Yes, if the location directory is not empty, CTAS with location will throw AnalysisException
```
sql("""create table ctas2 location '/tmp/u2' as select * from demo_CTAS""")
```
```
org.apache.spark.sql.AnalysisException: CREATE-TABLE-AS-SELECT cannot create table with location to a non-empty directory /tmp/u2 . To allow overwriting the existing non-empty directory, set 'spark.sql.legacy.allowNonEmptyLocationInCTAS' to true.
```
`CREATE TABLE AS SELECT` with non-empty `LOCATION` will throw `AnalysisException`. To restore the behavior before Spark 3.2, need to set `spark.sql.legacy.allowNonEmptyLocationInCTAS` to `true`. , default value is `false`.
Updated SQL migration guide.

### What changes were proposed in this pull request?
1. In HadoopMapReduceCommitProtocol, create parent directory before renaming custom partition path staging files
2. In InMemoryCatalog and HiveExternalCatalog, create new partition directory before renaming old partition path
3. Check return value of FileSystem#rename, if false, throw exception to avoid silent data loss cause by rename failure
4. Change DebugFilesystem#rename behavior to make it match HDFS's behavior (return false without rename when dst parent directory not exist)
### Why are the changes needed?
Depends on FileSystem#rename implementation, when destination directory does not exist, file system may
1. return false without renaming file nor throwing exception (e.g. HDFS), or
2. create destination directory, rename files, and return true (e.g. LocalFileSystem)
In the first case above, renames in HadoopMapReduceCommitProtocol for custom partition path will fail silently if the destination partition path does not exist. Failed renames can happen when
1. dynamicPartitionOverwrite == true, the custom partition path directories are deleted by the job before the rename; or
2. the custom partition path directories do not exist before the job; or
3. something else is wrong when file system handle `rename`
The renames in MemoryCatalog and HiveExternalCatalog for partition renaming also have similar issue.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Modified DebugFilesystem#rename, and added new unit tests.
Without the fix in src code, five InsertSuite tests and one AlterTableRenamePartitionSuite test failed:

### What changes were proposed in this pull request?
SPARK-35253 upgraded janino from 3.0.16 to 3.1.4, `ClassBodyEvaluator` provides the `getBytecodes` method to get
the mapping from `ClassFile#getThisClassName` to `ClassFile#toByteArray` directly in this version and we don't need to get this variable by reflection api anymore.
So the main purpose of this pr is simplify the way to get `bytecodes` from `ClassBodyEvaluator` in `CodeGenerator#updateAndGetCompilationStats` method.
### Why are the changes needed?
Code simplification.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
- Pass the Jenkins or GitHub Action
- Manual test:
1. Define a code fragment to be tested, for example:
```
val codeBody = s"""
public java.lang.Object generate(Object[] references) {
return new TestMetricCode(references);
}
class TestMetricCode {
public TestMetricCode(Object[] references) {
}
public long sumOfSquares(long left, long right) {
return left * left + right * right;
}
}
"""
```
2. Create a `ClassBodyEvaluator` and `cook` the `codeBody` as above, the process of creating `ClassBodyEvaluator` can extract from `CodeGenerator#doCompile` method.
3. Get `bytecodes` using `ClassBodyEvaluator#getBytecodes` api(after this pr) and reflection api(before this pr) respectively, then assert that they are the same. If the `bytecodes` not changed, we can be sure that metrics state will not change. The test code example as follows:
```
import scala.collection.JavaConverters._
val bytecodesFromApi = evaluator.getBytecodes.asScala
val bytecodesFromReflectionApi = {
val scField = classOf[ClassBodyEvaluator].getDeclaredField("sc")
scField.setAccessible(true)
val compiler = scField.get(evaluator).asInstanceOf[SimpleCompiler]
val loader = compiler.getClassLoader.asInstanceOf[ByteArrayClassLoader]
val classesField = loader.getClass.getDeclaredField("classes")
classesField.setAccessible(true)
classesField.get(loader).asInstanceOf[java.util.Map[String, Array[Byte]]].asScala
}
assert(bytecodesFromApi == bytecodesFromReflectionApi)
```

### What changes were proposed in this pull request?
To pass the TPCDS-related plan stability tests in scala-2.13, this PR proposes to fix two things below;
- (1) Sorts elements in the predicate `InSet` and the source filter `In` for printing their nodes.
- (2) Formats nested collection elements (`Seq`, `Array`, and `Set`) recursively in `TreeNode.argString`.
As for (1), it seems v2.12/v2.13 prints `Set` elements with a different order, so we need to sort them explicitly. As for (2), the `Seq` implementation is different between v2.12/v2.13, so we need to format nested `Seq` elements correctly to hide the name of its implementation (See an example below);
```

Spark doesn't support aggregate functions with mixed outer and local references. This PR applies this check earlier to fail with a clear error message instead of some weird ones, and simplifies the related code in `SubExprUtils.getOuterReferences`. This PR also refines the error message a bit.
### Why are the changes needed?
better error message
### Does this PR introduce _any_ user-facing change?
no
### How was this patch tested?

Introduction: this PR is a part of SPARK-10816 (`EventTime based sessionization (session window)`). Please refer #31937 to see the overall view of the code change. (Note that code diff could be diverged a bit.)
### What changes were proposed in this pull request?
This PR introduces UpdatingSessionsIterator, which analyzes neighbor elements and adjust session information on elements.
UpdatingSessionsIterator calculates and updates the session window for each element in the given iterator, which makes elements in the same session window having same session spec. Downstream can apply aggregation to finally merge these elements bound to the same session window.
UpdatingSessionsIterator works on the precondition that given iterator is sorted by "group keys + start time of session window", and the iterator still retains the characteristic of the sort.
UpdatingSessionsIterator copies the elements to safely update on each element, as well as buffers elements which are bound to the same session window. Due to such overheads, MergingSessionsIterator which will be introduced via SPARK-34889 should be used whenever possible.
This PR also introduces UpdatingSessionsExec which is the physical node on leveraging UpdatingSessionsIterator to sort the input rows and updates session information on input rows.
### Why are the changes needed?
This part is a one of required on implementing SPARK-10816.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
New test suite added.

### What changes were proposed in this pull request?
Move hash map lookup operation out of `InvokeLike.invoke` since it doesn't depend on the input.
### Why are the changes needed?
We shouldn't need to look up the hash map for every input row evaluated by `InvokeLike.invoke` since it doesn't depend on input. This could speed up the performance a bit.

### What changes were proposed in this pull request?
Generally, we would expect that x = y => hash( x ) = hash( y ). However +-0 hash to different values for floating point types.
```
scala> spark.sql("select hash(cast('0.0' as double)), hash(cast('-0.0' as double))").show
+-------------------------+--------------------------+
|hash(CAST(0.0 AS DOUBLE))|hash(CAST(-0.0 AS DOUBLE))|
+-------------------------+--------------------------+
| -1670924195| -853646085|
+-------------------------+--------------------------+
scala> spark.sql("select cast('0.0' as double) == cast('-0.0' as double)").show
+--------------------------------------------+
|(CAST(0.0 AS DOUBLE) = CAST(-0.0 AS DOUBLE))|
+--------------------------------------------+
| true|
+--------------------------------------------+
```
Here is an extract from IEEE 754:
> The two zeros are distinguishable arithmetically only by either division-byzero ( producing appropriately signed infinities ) or else by the CopySign function recommended by IEEE 754 /854. Infinities, SNaNs, NaNs and Subnormal numbers necessitate four more special cases
From this, I deduce that the hash function must produce the same result for 0 and -0.
### Why are the changes needed?
It is a correctness issue
### Does this PR introduce _any_ user-facing change?
This changes only affect to the hash function applied to -0 value in float and double types
### How was this patch tested?

### What changes were proposed in this pull request?
Add New SQL functions:
* TRY_ADD
* TRY_DIVIDE
These expressions are identical to the following expression under ANSI mode except that it returns null if error occurs:
* ADD
* DIVIDE
Note: it is easy to add other expressions like `TRY_SUBTRACT`/`TRY_MULTIPLY` but let's control the number of these new expressions and just add `TRY_ADD` and `TRY_DIVIDE` for now.
### Why are the changes needed?
1. Users can manage to finish queries without interruptions in ANSI mode.
2. Users can get NULLs instead of unreasonable results if overflow occurs when ANSI mode is off.
For example, the behavior of the following SQL operations is unreasonable:
```
2147483647 + 2 => -2147483647
```
With the new safe version SQL functions:
```
TRY_ADD(2147483647, 2) => null
```
Note: **We should only add new expressions to important operators, instead of adding new safe expressions for all the expressions that can throw errors.**
### Does this PR introduce _any_ user-facing change?
Yes, new SQL functions: TRY_ADD/TRY_DIVIDE

### What changes were proposed in this pull request?
In Spark, we have an extension in the MERGE syntax: INSERT/UPDATE *. This is not from ANSI standard or any other mainstream databases, so we need to define the behaviors by our own.
The behavior today is very weird: assume the source table has `n1` columns, target table has `n2` columns. We generate the assignments by taking the first `min(n1, n2)` columns from source & target tables and pairing them by ordinal.
This PR proposes a more reasonable behavior: take all the columns from target table as keys, and find the corresponding columns from source table by name as values.
### Why are the changes needed?
Fix the MEREG INSERT/UPDATE * to be more user-friendly and easy to do schema evolution.
### Does this PR introduce _any_ user-facing change?
Yes, but MERGE is only supported by very few data sources.

### What changes were proposed in this pull request?
Change `map` in `InvokeLike.invoke` to a while loop to improve performance, following Spark [style guide](https://github.com/databricks/scala-style-guide#traversal-and-zipwithindex).
### Why are the changes needed?
`InvokeLike.invoke`, which is used in non-codegen path for `Invoke` and `StaticInvoke`, currently uses `map` to evaluate arguments:
```scala
val args = arguments.map(e => e.eval(input).asInstanceOf[Object])
if (needNullCheck && args.exists(_ == null)) {
// return null if one of arguments is null
null
} else {
...
```
which is pretty expensive if the method itself is trivial. We can change it to a plain while loop.

### What changes were proposed in this pull request?
This PR proposes to bump up the janino version from 3.0.16 to v3.1.4.
The major changes of this upgrade are as follows:
- Fixed issue #131: Janino 3.1.2 is 10x slower than 3.0.11: The Compiler's IClassLoader was initialized way too eagerly, thus lots of classes were loaded from the class path, which is very slow.
- Improved the encoding of stack map frames according to JVMS11 4.7.4: Previously, only "full_frame"s were generated.
- Fixed issue #107: Janino requires "org.codehaus.commons.compiler.io", but commons-compiler does not export this package
- Fixed the promotion of the array access index expression (see JLS7 15.13 Array Access Expressions).
For all the changes, please see the change log: http://janino-compiler.github.io/janino/changelog.html
NOTE1: I've checked that there is no obvious performance regression. For all the data, see a link: https://docs.google.com/spreadsheets/d/1srxT9CioGQg1fLKM3Uo8z1sTzgCsMj4pg6JzpdcG6VU/edit?usp=sharing
NOTE2: We upgraded janino to 3.1.2 (#27860) once before, but the commit had been reverted in #29495 because of the correctness issue. Recently, #32374 had checked if Spark could land on v3.1.3 or not, but a new bug was found there. These known issues has been fixed in v3.1.4 by following PRs:
- janino-compiler/janino#145
- janino-compiler/janino#146
### Why are the changes needed?
janino v3.0.X is no longer maintained.

### What changes were proposed in this pull request?
In `ApplyFunctionExpression`, move `zipWithIndex` out of the loop for each input row.
### Why are the changes needed?
When the `ScalarFunction` is trivial, `zipWithIndex` could incur significant costs, as shown below:
<img width="899" alt="Screen Shot 2021-05-11 at 10 03 42 AM" src="https://user-images.githubusercontent.com/506679/117866421-fb19de80-b24b-11eb-8c94-d5e8c8b1eda9.png">
By removing it out of the loop, I'm seeing sometimes 2x speedup from `V2FunctionBenchmark`. For instance:
Before:
```

native_long_add 32437 32896 434 15.4 64.9 1.0X
java_long_add_default 85675 97045 NaN 5.8 171.3 0.4X
```
After:
```

After https://github.com/apache/spark/pull/31349, the function becomes:
```

The column metadata is used in a few places such as re-constructing CHAR/VARCHAR information such as in [SPARK-33901](https://issues.apache.org/jira/browse/SPARK-33901). Therefore, we should retain the info during nested column pruning.

### What changes were proposed in this pull request?
This allows `ScalarFunction` implemented in Java to optionally specify the magic method `invoke` to be static, which can be used if the UDF is stateless. Comparing to the non-static method, it can potentially give better performance due to elimination of dynamic dispatch, etc.
Also added a benchmark to measure performance of: the default `produceResult`, non-static magic method and static magic method.
### Why are the changes needed?
For UDFs that are stateless (e.g., no need to maintain intermediate state between each function call), it's better to allow users to implement the UDF function as static method which could potentially give better performance.
### Does this PR introduce _any_ user-facing change?
Yes. Spark users can now have the choice to define static magic method for `ScalarFunction` when it is written in Java and when the UDF is stateless.
### How was this patch tested?

### What changes were proposed in this pull request?
This patch proposes to make StaticInvoke able to find method with given method name even the parameter types do not exactly match to argument classes.
### Why are the changes needed?
Unlike `Invoke`, `StaticInvoke` only tries to get the method with exact argument classes. If the calling method's parameter types are not exactly matched with the argument classes, `StaticInvoke` cannot find the method.
`StaticInvoke` should be able to find the method under the cases too.
### Does this PR introduce _any_ user-facing change?
Yes. `StaticInvoke` can find a method even the argument classes are not exactly matched.
### How was this patch tested?
