-------------------------------------
Summary: Create a backend flag to control tuple-analysis in
AggregationNode
Key: IMPALA-13637
URL: https://issues.apache.org/jira/browse/IMPALA-13637
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Riza Suminto
Assignee: Riza Suminto
IMPALA-13405 adds a new tuple-analysis logic in AggregationNode to lower
cardinality estimation when dealing with multi-column grouping. It is good to
have control flag in case the old behavior is preferred.
