[SPARK-27043][SQL] Add ORC nested schema pruning benchmarks ## What changes were proposed in this pull request? We have benchmark of nested schema pruning, but only for Parquet. This adds similar benchmark for ORC. This is used with nested schema pruning of ORC. ## How was this patch tested? Added test. Closes #23955 from viirya/orc-nested-schema-pruning-benchmark.

[SPARK-27701][SQL] Extend NestedColumnAliasing to general nested field cases including GetArrayStructField ## What changes were proposed in this pull request? `NestedColumnAliasing` rule covers `GetStructField` only, currently. It means that some nested field extraction expressions aren't pruned. For example, if only accessing a nested field in an array of struct (`GetArrayStructFields`), this column isn't pruned. This patch extends the rule to cover general nested field cases, including `GetArrayStructFields`. ## How was this patch tested? Added tests. Closes #24599 from viirya/nested-pruning-extract-value.

[SPARK-27701][SQL] Extend NestedColumnAliasing to general nested field cases including GetArrayStructField ## What changes were proposed in this pull request? `NestedColumnAliasing` rule covers `GetStructField` only, currently. It means that some nested field extraction expressions aren't pruned. For example, if only accessing a nested field in an array of struct (`GetArrayStructFields`), this column isn't pruned. This patch extends the rule to cover general nested field cases, including `GetArrayStructFields`. ## How was this patch tested? Added tests. Closes #24599 from viirya/nested-pruning-extract-value.

[SPARK-27043][SQL] Add ORC nested schema pruning benchmarks ## What changes were proposed in this pull request? We have benchmark of nested schema pruning, but only for Parquet. This adds similar benchmark for ORC. This is used with nested schema pruning of ORC. ## How was this patch tested? Added test. Closes #23955 from viirya/orc-nested-schema-pruning-benchmark.
