Que is a high-performance job queue that improves the reliability of your
|
|
application by protecting your jobs with the same ACID guarantees as the rest of
|
|
your data.
|
|
|
|
Que is a queue for Ruby and PostgreSQL that manages jobs using advisory locks,
|
|
which gives it several advantages over other RDBMS-backed queues:
|
|
- Concurrency - Workers don't block each other when trying to lock jobs, as
|
|
often occurs with "SELECT FOR UPDATE"-style locking. This allows for very high
|
|
throughput with a large number of workers.
|
|
- Efficiency - Locks are held in memory, so locking a job doesn't incur a disk
|
|
write. These first two points are what limit performance with other queues.
|
|
Under heavy load, Que's bottleneck is CPU, not I/O.
|
|
- Safety - If a Ruby process dies, the jobs it's working won't be lost, or left
|
|
in a locked or ambiguous state - they immediately become available for any
|
|
other worker to pick up.
