----------------------------------
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.
