Job queue

Serialize jobs – queues prevent parallel runs and deadlocks.

On this page

The job queue complements job control: jobs in the same queue do not run in parallel but sequentially. This avoids overlaps and deadlocks.

Use cases

Two tightly scheduled jobs access the same database objects – if they overlap a deadlock may occur. Same queue → job B starts only after job A.
A per-minute job A and a twice-daily job B should never run at the same time – same queue → A pauses while B runs.
