Change subject: IMPALA-12881: Use getFkPkJoinCardinality to reduce scan cardinality ...................................................................... IMPALA-12881: Use getFkPkJoinCardinality to reduce scan cardinality IMPALA-12018 adds reduceCardinalityForScanNode to lower cardinality estimation when runtime filter is involved. It calls JoinNode.computeGenericJoinCardinality(). However, if the originating join node has FK-PK conjunct, it should be possible to obtain lower cardinality estimate by calling JoinNode.getFkPkJoinCardinality() instead. This patch adds those analysis and call JoinNode.getFkPkJoinCardinality() when possible. It is, however, only limited for runtime filter that evaluates on storage layer to avoid severe underestimation. Runtime filter that evaluate at scan node at row level will keep using JoinNode.computeGenericJoinCardinality(). Testing: - Update TpcdsCpuCostPlannerTest.
