--------------------------------------
Summary: Add test that compute stats does not result in a
different tuple cache key
Key: IMPALA-13188
URL: https://issues.apache.org/jira/browse/IMPALA-13188
Project: IMPALA
Issue Type: Task
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
If someone runs "compute stats" on the underlying tables for a query, the tuple
cache key should only change if the plan actually changes. The resource
estimates should not be incorporated into the tuple cache key as they have no
semantic impact. The code already excludes the resource estimates from the key
for the PlanNode, but we should have tests for computing stats and verifying
that the key doesn't change.
