Summary: Add hash tracing for the tuple cache's runtime key
Key: IMPALA-14191
URL: https://issues.apache.org/jira/browse/IMPALA-14191
Project: IMPALA
Issue Type: Task
Components: Backend
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
The planner keeps a hash trace for contributions to the planning-time tuple
cache key. This is useful for debugging. There is no equivalent functionality
for the runtime key (which is hashing scan ranges, etc). The runtime key is
getting more complicated, so we should add a cache key trace for the runtime
key. We will need a way to compute/display it only when requested.
