[jira] [Created] (SPARK-29065) Extend `EXTRACT` benchmark

Maxim Gekk created SPARK-29065:
----------------------------------

             Summary: Extend `EXTRACT` benchmark
                 Key: SPARK-29065
                 URL: https://issues.apache.org/jira/browse/SPARK-29065
             Project: Spark
          Issue Type: Test
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Maxim Gekk


Extend `ExtractBenchmark` and add new ones for:
- `EXTRACT` and `DATE` as input column
- the `DATE_PART` function and `DATE`/`TIMESTAMP` input column

Some of sub-expressions of `EXTRACT` and `DATE_PART` 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`.
