---------------------------------------
Summary: Consider IN-list filters in partitioned joins
Key: IMPALA-11142
URL: https://issues.apache.org/jira/browse/IMPALA-11142
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Reporter: Quanlong Huang
We currently skip generating runtime IN-list filter for partitioned joins,
because they are likely to exceeds the entry limit (1024) on the build side,
leading the IN-list filter being disabled. However, the build side can still be
small if it has selective predicates. We should consider enabling runtime
IN-list filters based on the estimated cardinality of partitioned joins.
Run some perf tests to decide this.
