A PG (Process Groups) based notifier implementation that runs with Distributed Erlang.

Distributed Erlang

PG requires a functional Distributed Erlang cluster to broadcast between nodes. If your application isn't clustered, then you should consider an alternative notifier such as Oban.Notifiers.Postgres

Usage

Specify the PG notifier in your Oban configuration:

config :my_app, Oban,
  notifier: Oban.Notifiers.PG,
  ...

By default, all Oban instances using the same prefix option will receive notifications from each other. You can use the namespace option to separate instances that are in the same cluster without changing the prefix:

config :my_app, Oban,
  notifier: {Oban.Notifiers.PG, namespace: :custom_namespace}
  ...

The namespace may be any term.
