------------------------------------
Summary: Push 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
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.
