Bump oban from 2.17.12 to 2.19.0

[dependabot]

Bumps oban from 2.17.12 to 2.19.0.

Release notes

Sourced from oban's releases.

v2.19

The minimum Elixir version is now v1.15. The official policy is to only support the three latest versions of Elixir.

🐬 MySQL Support

Oban officially supports MySQL with the new Dolphin engine. Oban supports modern (read "with full JSON support") MySQL versions from 8.4 on, and has been tested on the highly scalable Plantescale database.

Running on MySQL is as simple as specifying the Dolphin engine in your configuration:

config :my_app, Oban,
  engine: Oban.Engines.Dolphin,
  queues: [default: 10],
  repo: MyApp.Repo

With this addition, Oban can run in estimated 10% more Elixir applications!

⚗️ Automated Installer

Installing Oban into a new application is simplified with a new igniter powered mix task. The new oban.install task handles installing and configuring a standard Oban installation, and it will deduce the correct engine and notifier automatically based on the database adapter.

mix igniter.install oban

This oban.install task is currently the recommended way to install Oban. As a bonus, the task composes together with other igniter installers, making it possible to install phoenix, ash, oban, and other packages with a single command:

mix igniter.install phoenix ash_phoenix ash_postgres ash_oban

Look at the Mix.Oban.Install docs for full usage and options.

📔 Logging Enhancements

Logging in a busy system may be noisy due to job events, but there are other events that are particularly useful for diagnosing issues. A new events option for attach_default_logger/1 allows selective event logging, so it's possible to receive important notices such as notifier connectivity issues, without logging all job activity:

Oban.Telemetry.attach_default_logger(events: ~w(notifier peer stager)a)

Changelog

Sourced from oban's changelog.

v2.19.0 — 2025-01-16

Enhancements

• [Oban] Start all queues in parallel on initialization.

  The midwife now starts queues using an async stream to parallelize startup and minimize boot time for applications with many queues. Previously,

• [Oban] Safely return nil from check_queue/2 when checking queues that aren't running.

  Checking on a queue that wasn't currently running on the local node now returns nil rather than causing a crash. This makes it safer to check the whether a queue is running at all without a try/catch clause.

• [Oban] Add check_all_queues/1 to gather all queue status in a single function.

  This new helper gathers the "check" details from all running queues on the local node. While it was previously possible to pull the queues list from config and call check_queue/2 on each entry, this more accurately pulls from the registry and checks each producer concurrently.

• [Oban] Add delete_job/2 and delete_all_jobs/2 operations.

  This adds Oban.delete_job/2, Oban.delete_all_jobs/2, Engine callbacks, and associated operations for all native engines. Deleting jobs is now easier and safer, due to automatic state protections.

• [Engine] Record when a queue starts shutting down

  Queue producer metadata now includes a shutdown_started_at field to indicate that a queue isn't just paused, but is actually shutting down as well.

• [Engine] Add rescue_jobs/3 callback for all engines.

  The Lifeline plugin formerly used two queries to rescue jobs—one to mark jobs with remaining attempts as available and another that discarded the remaining stuck jobs. Those are now combined into a single callback, with the base definition in the Basic engine.

  MySQL won't accept a select in an update statement. The Dolphin implementation of rescue_jobs/3 uses multiple queries to return the relevant telemetry data and make multiple updates.

• [Cron] Introduce Oban.Cron with schedule_interval/4

  The new Cron module allows processes, namely plugins, to get cron-like scheduled functionality with a single function call. This will allow plugins to removes boilerplate around parsing, scheduling, and evaluating for cron behavior.

• [Registry] Add select/1 to simplify querying for registered modules.
