> Project: IMPALA

> Affects Versions: Impala 4.5.0
> Reporter: Joe McDonnell
> Assignee: Michael Smith
> Priority: Major
> Fix For: Impala 4.5.0

>
> 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.
