[jira] [Created] (CALCITE-1333) AggFunctions supported by JdbcAggregate should depend on SqlKind, instead of operator instance

MinJi Kim created CALCITE-1333:
----------------------------------

             Summary: AggFunctions supported by JdbcAggregate should depend on SqlKind, instead of operator instance
                 Key: CALCITE-1333
                 URL: https://issues.apache.org/jira/browse/CALCITE-1333
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: MinJi Kim
            Assignee: Julian Hyde


In JdbcAggregate, there is a list of functions that can be implemented and therefore pushed into the underlying database.  The list of functions use operator instance to check, but it would be better to use SqlKind.  This is particularly relevant in case a user creates his own operators (e.g. Drill wraps some of calcite's operators), so comparing instances does not work.
