-------------------------------------
Summary: ExchangeNode should use getFilteredCardinality for
costing.
Key: IMPALA-12703
URL: https://issues.apache.org/jira/browse/IMPALA-12703
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Riza Suminto
Assignee: Riza Suminto
IMPALA-12018 changed the CPU costing formula from using getCardinality() to
getFilteredCardinality() for DataStreamSink, HashJoinNode, JoinNode, and
NestedLoopJoinNode. However, it miss to do the same for ExchangeNode, which is
also eligible for cardinality reduction by runtime filter.
