Resolution: Duplicate
> Perform parquet filter pushdown in logical planning.

> Key: DRILL-4997
> URL: https://issues.apache.org/jira/browse/DRILL-4997
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Reporter: Jinfeng Ni
>
> DRILL-1950 put parquet filter pushdown rule in physical planning phase, after
> all join order related tasks have been done. Main reason for doing this is
> we want to reduce the performance regression possibility caused by a
> different join order, as a result of reduced row count in scan operator.
> Ideally this should be done in logical planning, before join order planning
> is done. Before we can make such change, we have to figure out how to adjust
> the selectivity estimation of filter operator, after filter is pushed down to
> scan.
