Simple ActiveJob worker for PostgreSQL using LISTEN/NOTIFY and SKIP LOCKED.

Supports most ActiveJob features like multiple queues, priorities and wait times.

Needs PostgreSQL 9.5 to use SKIP LOCKED.

Just schedule your work with ActiveJob, then run one or multiple workers for the default queue with

$ bin/rails runner PgJobs.work

or for other queues with

$ bin/rails runner "PgJobs.work(:my_queue)"

Add this line to your application's Gemfile:

gem 'pg_jobs'

And then execute:

$ bundle

Then copy the migrations and migrate your database:

$ bin/rails railties:install:migrations
$ bin/rails db:migrate

To configure the ActiveJob adapter add this to your environment configuration (config/environments/production.rb):

config.active_job.queue_adapter = :pg_jobs
