[jira] [Created] (IMPALA-15484) Calcite planner: Support temporal TRUNC overloads

Aleksandr Efimov created IMPALA-15484:
-----------------------------------------

             Summary: 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


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.
