rails/activejob/CHANGELOG.md

• Make Active Job transaction aware when used conjointly with Active Record.

  A common mistake with Active Job is to enqueue jobs from inside a transaction, causing them to potentially be picked and ran by another process, before the transaction is committed, which may result in various errors.

  Topic.transaction do
    topic = Topic.create(...)
    NewTopicNotificationJob.perform_later(topic)
  end
  

  Now Active Job will automatically defer the enqueuing to after the transaction is committed, and drop the job if the transaction is rolled back.

  Various queue implementations can choose to disable this behavior, and users can disable it, or force it on a per job basis:

  class NewTopicNotificationJob < ApplicationJob
    self.enqueue_after_transaction_commit = :never # or `:always` or `:default`
  end
