dop_value	integer	DOP value obtained by the statement from the resource pool
control_group	text	Cgroup currently used by the statement
status	text	Status of the statement, including: pending: waiting to be executed running: being executed finished: finished normally (If enqueue is set to StoredProc or Transaction, this state indicates that only a part of jobs in the statement has been executed.
