|LAUNCHED||The launched. At this point the query is launched for execution.|
|RUNNING||The running. At this point the query starts running on chosen driver|
|EXECUTED||The executed. At this point execution is finished by driver, but server may still have some more operations pending like result persistence, if enabled.|
|FAILING||This state is when depending on retry policy, either the query moves to QUEUED (in case retries are to be done), or to FAILED.|
|SUCCESSFUL||The successful. At this point all operations related to the query are finished successfully by driver and server.|
