[GitHub] [pinot] Jackie-Jiang commented on issue #9660: column data type is always STRING when results are empty.

   When no row selected, we can consider returning empty result table (no data schema, no row) in the broker response. Another related issue is for aggregation query: #9531. There is indeed backward compatible concern around this change when the client/user expects non-empty result table (with data schema but no row).
   Can you please also check the behavior for other query engines when there is no row selected? E.g. Presto, Postgres, MySQL
