[jira] [Created] (CALCITE-1347) Druid adapter column detection misses strings

Gian Merlino created CALCITE-1347:
-------------------------------------

             Summary: Druid adapter column detection misses strings
                 Key: CALCITE-1347
                 URL: https://issues.apache.org/jira/browse/CALCITE-1347
             Project: Calcite
          Issue Type: Bug
          Components: druid
            Reporter: Gian Merlino
            Assignee: Julian Hyde


Currently string columns aren't detected because "isSupportedType" doesn't include them.

Also, I think there isn't any need to add to fieldBuilder while scanning the "aggregators" - that map contains the aggregate functions used to create the metric columns, but the metric columns are still in "columns" anyway.

Patch: https://github.com/apache/calcite/pull/268
