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.

  # admission loop with the wrong context (job.arguments is still []
  # at that point because ActiveJob defers deserialization).
