---------------------------------------
Summary: Ignore AnalyticEvalNode if analytic results are not used
as group-by/join keys
Key: IMPALA-15590
URL: https://issues.apache.org/jira/browse/IMPALA-15590
Project: IMPALA
Issue Type: Improvement
Reporter: Quanlong Huang
AnalyticEvalNode appends analytic results to the input tuples as new columns.
If these columns are not used as group-by/join keys in downstream nodes, e.g.
they don't matter in downstream cardinality, we can ignore AnalyticEvalNode in
the HBO key string of downstream nodes.
