 # pgqueue
 
+**A background job queue that runs on the PostgreSQL you already have.** No Redis, no
+RabbitMQ, no second system to operate, back up and keep consistent with your data.

+**[Live demo](https://pgqueue.maciejzielinski.dev)** · [Status](https://status.maciejzielinski.dev) · [Portfolio](https://maciejzielinski.dev)
+
+The live demo is a read-only dashboard over a synthetic workload on a real PostgreSQL. Watch jobs retry, die and get recovered after a worker is killed.

 pgqueue is a small job queue library built around one PostgreSQL feature: `SELECT … FOR UPDATE SKIP LOCKED`. It gives you typed tasks, retries
 with backoff, a dead-letter state, scheduled and cron jobs, crash recovery through leases,
 LISTEN/NOTIFY wake-ups, a dashboard and Prometheus metrics, and it lets you enqueue a job
 **in the same transaction** as the data it refers to.
