Oban v2.4.3
Oban

Changelog

All notable changes to Oban.Pro will be documented in this file.

v0.6.1 — 2021-01-28

Fixed

  • [Oban.Pro.Plugins.Lifeline] Consider fully qualified node identities when rescuing potential orphans. The previous version could erroneously rescue executing jobs.

v0.6.0 — 2021-01-26

Changed

  • [Oban.Pro.Plugins.Lifeline] Record fully qualified node identities (combining the Oban supervisor name and the host name). This allows Oban Web to track beats recorded by the same host but different instances.

  • Enhance all plugin span metadata with details such as how many jobs were pruned, inserted, reprioritized, etc. Telemetry events and metadata for all Pro plugins now matches the events from Oban OSS.

  • Bump Oban dependency to ~> 2.4.0 due to CRON parser changes and improved telemetry span events.

Fixed

  • [Oban.Pro.Plugins.Workflow] Correct typespecs for new_workflow/1 and libgraph related functions.

  • [Oban.Pro.Plugins.DynamicCron] Support inserting and retrieving cron records with a custom prefix. All operations are wrapped in a Multi, which ignored the outer transaction's prefix.

v0.5.3 — 2020-12-09

  • [Oban.Pro.Plugins.DynamicPruner] Consider cancelled jobs that were never attempted when pruning.

v0.5.2 — 2020-11-27

  • [Oban.Pro.Plugins.BatchManager] Check for the correct output from Worker.from_string, fixing callback insertion.

v0.5.1 — 2020-11-06

  • [Oban.Pro.Plugins.DynamicPruner] Allow state overrides when pruning cancelled jobs.

v0.5.0 — 2020-11-06

  • [Oban.Pro.Workers.Workflow] A new worker that composes arbitrary jobs together for directed execution. This allows sequential, fan-out and fan-in workflows that are horizontally distributed and fault tolerant.

    See the Workflow docs for setup and a walk-through with use-cases.

  • Bump Oban dependency to ~> 2.3.0 due to the workflow worker's use of the new meta field in Oban.Job.

v0.4.2 — 2020-10-19

  • [Oban.Pro.Plugins.DynamicPruner] Always delete oldest job when pruning in max_len mode. In max_len mode, when job insertion exceeded job pruning the oldest jobs would persist between prunes.

v0.4.1 — 2020-10-11

Changed

v0.4.0 — 2020-10-05

Added

  • [Oban.Pro.Plugins.DynamicCron] The DynamicCron plugin is a replacement for Oban's built in cron scheduler. It supports adding, updating, deleting, pausing and resuming periodic jobs at runtime and boot time. It is an ideal solution for applications that must dynamically start and manage scheduled tasks at runtime.

    See the DynamicCron installation docs for instructions on getting started.

  • [Oban.Pro.Plugins.Lifeline] Add :retry_exhausted option, which will retry exhausted jobs rather than discard them while rescuing.

Breaking Change

  • Emit standardized [:oban, :plugin, :start | :stop | :exception] events for all plugins. Previously, each plugin would emit its own event, which required extensive :telemetry.attach_many calls. Now all plugins have a standard event name with differentiated metatada, including a :plugin key with the module name responsible for emitting the event.

    To upgrade replace any events that used :prune, :lifeline or :reprioritizer with :plugin. For example, [:oban, :prune, :start] is now [:oban, :plugin, :start] with the metadata %{plugin: DynamicPruner}.

v0.3.2 — 2020-08-28

  • [Oban.Pro.Plugins.DynamicPruner] Correctly prune discarded jobs that were cancelled before they were ever attempted.

v0.3.1 — 2020-08-05

Fixed

  • [Oban.Pro.Workers.Batch] Only invoke batch callbacks that are defined for the current worker.

v0.3.0 — 2020-07-10

Fixed

  • [Oban.Pro.Plugins.Lifeline] Ignore unknown messages to the plugin to prevent crashes.

Changed

  • Bump Oban dependency to 2.0.0

v0.2.1 — 2020-07-01

Added

  • Add handle_exhausted/1 callback to Oban.Pro.Workers.Batch worker. This new callback is triggered when all jobs are either completed or discarded.

v0.2.0 — 2020-06-12

Fixed

  • Conditional improvements to the BatchManager plugin

Changed

  • Bump Oban dependency to 2.0.0-rc.1

v0.1.0 — 2020-06-03

  • Oban.Pro.Plugins.BatchManager
  • Oban.Pro.Plugins.DynamicPruner
  • Oban.Pro.Plugins.Lifeline
