    Description

      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.
