v2.18.2

Bug Fixes

• [Repo] Prevent debug noise by ensuring default opts for standard transactions.

  Without default opts each transaction is logged. Many standard operations execute each second, which makes for noisy logs. Now transaction opts are passed as a third argument to ensure defaults are applied.

• [Repo] Increase transaction retry delay and increase with each attempt.

  Bump the base transaction retry from 100ms to 500ms, and increase linearly between each successive attempt to provide deeper backoff. This alleviates pressure on smaller connection pools and gives more time to recover from contentions failures.

v2.18.1

Enhancements

• [Repo] Automatically retry all transactions with backoff.

  Avoid both expected an unexpected database errors by automatically retrying transactions. Some operations, such as serialization and lock not available errors, are likely to occur during standard use depending on how a database is configured. Other errors happen infrequently due to pool contention or flickering connections, and those should also be retried for increased safety.

  This change is applied to Oban.Repo.transaction/3 itself, so it will apply to every location that uses transactions.

• [Migration] Declare tags as an array of text rather than varchar.

  We don't provide a limit on the size of tags and they could conceivably be larger than 256 characters. Externally the types are interchangeable, but internally there are minor advantages to using the text type.

  There isn't a new migration; this change is only for new tables.

Bug Fixes

• [Repo] Correctly dispatch query!/4 to query! rather than query without a bang.

v2.18.0

🔭 Queue Shutdown Telemetry

A new queue shutdown event, [:oban, :queue, :shutdown], is emitted by each queue when it terminates. The event originates from the watchman process, which tracks the total ellapsed time from when termination starts to when all jobs complete or the allotted period is exhausted.

Any jobs that take longer than the :shutdown_grace_period (by default 15 seconds) are brutally killed and left as orphans. The ids of jobs left in an executing state are listed in the event's orphaned meta.

This also adds queue:shutdown logging to the default logger. Only queues that shutdown with orphaned jobs are logged, which makes it easier to detect orphaned jobs and which jobs were affected:

[
  message: "jobs were orphaned because they didn't finish executing in the allotted time",
  queue: "alpha",
  source: "oban",
  event: "queue:shutdown",
  ellapsed: 500,
  orphaned: [101, 102, 103]
]

v2.18.0 — 2024-07-26

Enhancements

• [Job] Support simple unique: true and unique: false declarations

  Uniqueness can now be enabled with unique: true and disabled with unique: false from job options or a worker definition. The unique: true option uses all the standard defaults, but sets the period to :infinity for compatibility with Oban Pro's new simple unique mode.
