This guide walks you through maintaining a production Oban setup from an operational perspective.

Pruning Historic Jobs

Job stats and queue introspection are built on keeping job rows in the database after they have completed. This allows administrators to review completed jobs and build informative aggregates, at the expense of storage and an unbounded table size. To prevent the oban_jobs table from growing indefinitely, Oban actively prunes completed, cancelled, and discarded jobs.

By default, the pruner plugin retains jobs for 60 seconds. You can configure a longer retention period by providing a :max_age in seconds to the pruner plugin.

config :my_app, Oban,
  plugins: [{Oban.Plugins.Pruner, max_age: _5_minutes_in_seconds = 300}],
