-------------------------------------
Assignee: Maxim Gekk
> 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
> Assignee: Maxim Gekk
> Priority: Major
>
> 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()`
