Module: DispatchPolicy::JobExtension::BulkEnqueue

Defined in:
lib/dispatch_policy/job_extension.rb

Overview

Rails 7.1+ exposes ActiveJob.perform_all_later. We override it to route jobs declaring a dispatch_policy through a single bulk INSERT, while delegating jobs without a policy to the original enqueue_all path.

  # Critical: respect Bypass exactly like the per-job around_enqueue
  # does. Forwarder.dispatch deserializes admitted jobs and calls
  # ActiveJob.perform_all_later under Bypass.with — without this
  # check, BulkEnqueue would re-stage them, creating an infinite
  # admission loop with the wrong context (job.arguments is still []
  # at that point because ActiveJob defers deserialization).

  # Split exactly like the single path decides: jobs we own get staged,
  # everything else (no policy, unregistered policy name, or a retry on
  # a bypass_retries policy) goes straight to the adapter. Dropping them
  # — as a `next unless policy` inside the row builder would — silently
  # loses jobs the caller expected to be enqueued.
