             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.
