Rails Jobs

Job Configuration

• All jobs inherit from ApplicationJob
• Define queue_as at the top of the class; use :default, :low, or :critical
• Use Solid Queue in production (the Rails 8 default DB-backed runner; uses FOR UPDATE SKIP LOCKED)
• Prefer perform_later over perform_now for background execution
• For bulk enqueue, use ActiveJob.perform_all_later(job1, job2, ...) — single round-trip, no per-job callbacks
• For long-running, restart-safe work, use ActiveJob::Continuable with named step blocks (Rails 8.1+)

Transactional Enqueue

• Active Job defers enqueue until after the surrounding transaction commits (default since 7.2) — do not wrap perform_later in after_commit callbacks
• The per-job enqueue_after_transaction_commit override is deprecated in 8.0; rely on the default
• For ad-hoc post-commit work, use transaction do |t| t.after_commit { ... } end or ActiveRecord.after_all_transactions_commit { ... }
