--------------------------------------
Summary: Tuple cache keys should incorporate information about
related query options
Key: IMPALA-13186
URL: https://issues.apache.org/jira/browse/IMPALA-13186
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
Currently, the tuple cache key does not include information from the query
options. Many query options have no impact on the result of a query (e.g.
idle_session_timeout) or are evaluated purely on the coordinator during
planning (e.g. broadcast_bytes_limit).
However, some query options can impact behavior either by controlling how
certain things are calculated (e.g. decimal_v2) or controlling what conditions
result in an error. Changing a query option can change the output of a query.
We need some way to incorporate the relevant query options into the tuple cache
key so there is no correctness issue.
