Maxim Gekk created SPARK-30409:
----------------------------------
Summary: Use `NoOp` datasource in SQL benchmarks
Key: SPARK-30409
URL: https://issues.apache.org/jira/browse/SPARK-30409
Project: Spark
Issue Type: Test
Components: SQL
Affects Versions: 2.4.4
Reporter: Maxim Gekk
Currently, SQL benchmarks use `count()`, `collect()` and `foreach(_ => ())`
actions. The actions have additional overhead. For example, `collect()`
converts column values to external type values and pull data on the driver.
Need to unify benchmark and the `NoOp` datasource except the benchmarks for
`count()` or `collect()`
