The following commit(s) were added to refs/heads/master by this push: new 8e9fafb [SPARK-29065][SQL][TEST] Extend `EXTRACT` benchmark 8e9fafb is described below commit 8e9fafbb21a26028710df1831fc16b41855f0b4a Author: Maxim Gekk <max.g...@gmail.com> AuthorDate: Thu Sep 12 21:32:35 2019 +0900 [SPARK-29065][SQL][TEST] Extend `EXTRACT` benchmark ### What changes were proposed in this pull request? In the PR, I propose to extend `ExtractBenchmark` and add new ones for: - `EXTRACT` and `DATE` as input column - the `DATE_PART` function and `DATE`/`TIMESTAMP` input column ### Why are the changes needed? The `EXTRACT` expression is rebased on the `DATE_PART` expression by the PR https://github.com/apache/spark/pull/25410 where some of sub-expressions take `DATE` column as the input (`Millennium`, `Year` and etc.) but others require `TIMESTAMP` column (`Hour`, `Minute`). Separate benchmarks for `DATE` should exclude overhead of implicit conversions `DATE` <-> `TIMESTAMP`. ### Does this PR introduce any user-facing change? No, it doesn't. ### How was this patch tested? - Regenerated results of `ExtractBenchmark` Closes #25772 from MaxGekk/date_part-benchmark.
