------------------------------------
Fix Version/s: Impala 5.0.0
Resolution: Fixed
> Calcite planner: Support temporal TRUNC overloads
> -------------------------------------------------
>
> Key: IMPALA-15484
> URL: https://issues.apache.org/jira/browse/IMPALA-15484
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Aleksandr Efimov
> Assignee: Aleksandr Efimov
> Priority: Major
> Fix For: Impala 5.0.0
>
>
> Valid TRUNC(TIMESTAMP/DATE, STRING) calls fail in Calcite because the custom
> operator accepts only numeric arguments. Add temporal overload resolution
> through Impala's function resolver, keeping numeric inference unchanged. The
> candidate composes with IMPALA-14946 / Gerrit 24260 and passes 18 test
> methods and 84 strict HS2 executions.
