--------------------------------------
Summary: Improve heuristics for placing the tuple cache nodes
Key: IMPALA-13437
URL: https://issues.apache.org/jira/browse/IMPALA-13437
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
Improve placement of tuple cache nodes by considering:
# Selectivity
# Result Size
# Operator cost
# Data change frequency (maybe followup)
# Etc
This should avoid caching large results that don't have a major performance
improvement.
