> Unfortunately, if you try to cancel a query that's still in planing, the user RPC thread of the foreman Drillbit will block waiting for the query to finish planing, this will cause any other query submitted to the same Drillbit to block as well. It's a known issue (actually a serious Drill  limitation).
