### What changes were proposed in this pull request? This PR proposes move Parquet data source options from Python, Scala and Java into a single page. ### Why are the changes needed? So far, the documentation for Parquet data source options is separated into different pages for each language API documents. However, this makes managing many options inconvenient, so it is efficient to manage all options in a single page and provide a link to that page in the API of each language. ### Does this PR introduce _any_ user-facing change? Yes, the documents will be shown below after this change: - "Parquet Files" page ![Screen Shot 2021-05-21 at 1 35 08 PM](https://user-images.githubusercontent.com/44108233/119082866-e7375f00-ba39-11eb-9ade-a931a5957b34.png) - Python ![Screen Shot 2021-05-21 at 1 38 27 PM](https://user-images.githubusercontent.com/44108233/119082879-eef70380-ba39-11eb-9e8e-ee50eed98dbe.png) - Scala ![Screen Shot 2021-05-21 at 1 36 52 PM](https://user-images.githubusercontent.com/44108233/119082884-f1595d80-ba39-11eb-98d5-966657df65f7.png) - Java ![Screen Shot 2021-05-21 at 1 37 19 PM](https://user-images.githubusercontent.com/44108233/119082888-f4544e00-ba39-11eb-8bf8-47ce78ec0b01.png) ### How was this patch tested? Manually build docs and confirm the page. Closes #32161 from itholic/SPARK-34491. Authored-by: itholic <haejoon.lee@databricks.com> Signed-off-by: Hyukjin Kwon <gurwls223@apache.org> |

Spark SQL
This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.
Spark SQL is broken up into four subprojects:
- Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
- Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
- Hive Support (sql/hive) - Includes extensions that allow users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allow users to run queries that include Hive UDFs, UDAFs, and UDTFs.
- HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.
Running ./sql/create-docs.sh
generates SQL documentation for built-in functions under sql/site
, and SQL configuration documentation that gets included as part of configuration.md
in the main docs
directory.
