--------------------------------------
Summary: Calcite planner does not take advantage of the hash
partition of previous aggregates
Key: IMPALA-13451
URL: https://issues.apache.org/jira/browse/IMPALA-13451
Project: IMPALA
Issue Type: Sub-task
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
In [IMPALA-13197|http://issues.apache.org/jira/browse/IMPALA-13197], we added
support for analytic functions to the Calcite planner. The implementation
passes empty lists to the second two parameters of AnalyticPlanner. That
disables a small optimization which can avoid exchanges when the input is
already hash partitioned in a compatible way:

This is a tracking Jira just so we don't forget about this difference.
