Joe McDonnell created IMPALA-13945: -------------------------------------- Summary: Change the tuple cache key trace to display an individual node's contribution Key: IMPALA-13945 URL: https://issues.apache.org/jira/browse/IMPALA-13945 Project: IMPALA Issue Type: Task Components: Frontend Affects Versions: Impala 5.0.0 Reporter: Joe McDonnell
As tuple caching is supported higher in the plan tree, the cache key trace can become enormous, as it includes all of its childrens' information plus its own contribution. An individual trace can take up over a hundred lines in the profile. It can be hard to determine which contribution comes from which child. We should break up the hash trace and display each node's individual contribution to the hash trace. This should be smaller in the profile and more clearer display what is new at each level. -- This message was sent by Atlassian Jira (v8.20.10#820010)
