Here’s the proposal: • The query killer (DBConn.Kill) will be changed to proactively close the connection. This will cause the execution to return immediately During a shutdown, the state manager will use this list to kill all active queries if shutdown_grace_period is hit. This, along with the Kill change, will cause all those executes to immediately return
