Timo Walther updated FLINK-24717:
---------------------------------
Summary: Push down partitions before filters (was: Push partitions before
filters)
> Push down partitions before filters
> -----------------------------------
>
> Key: FLINK-24717
> URL: https://issues.apache.org/jira/browse/FLINK-24717
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Reporter: Timo Walther
> Priority: Major
>
> Currently, we push filters before partitions. This means that a
> {{applyFilters}} needs to have partition logic to extract the partition
> predicate. Furthermore, if a {{applyFilters}} consumes all filters (no
> remaining predicates), the {{applyPartitions}} is never called.
> We should execute the {{PushPartitionIntoTableSourceScanRule}} first and
> check for side effects of this change.
> See
> {{org.apache.flink.table.planner.plan.rules.logical.PushProjectIntoTableSourceScanRuleTest#testMetadataProjectionWithoutProjectionPushDownWhenNotSupportedAndNoneSelected}}
> for an example of using the new test infrastructure.
