Description

Currently, in the procedure scheduler, we will not schedule any other procedures for a given queue if a procedure has held the exclusive lock, even if a procedure does not require any locks. For such procedures that do not require locks, we prefer that they can be executed directly without waiting until the procedure that held the exclusive lock is executed before starting to schedule execution. Otherwise, if the procedure holding the exclusive lock is stuck, the procedure that does not need the lock will also wait forever.
