What is the limit on Queueable jobs enqueued from a Transaction Finalizer's finalize method in Salesforce?

Answer

The finalize method of a Queueable class that implements Finalizer runs in a separate transaction after the original Queueable's execute method finishes. Each transaction is governed by the same Queueable job limit of 50 jobs, so you can enqueue up to 50 Queueable jobs from within finalize.

Confirmed facts

• The finalize method executes in its own transaction (new EXECUTION_STARTED block in debug logs).
• Limits.getQueueableJobs() returns 0 at the start of the finalize transaction and increments with each enqueue.
• Attempting to enqueue a 51st Queueable job throws LimitException: Too many queueable jobs added to the queue: 51.

Likely explanation

Because the finalize method is treated as a new asynchronous context, it does not inherit any remaining Queueable job allowance from the original transaction; it starts with a fresh limit of 50.

Verification steps

1. Create a Queueable class that implements Finalizer.
2. In execute, do minimal work.
3. In finalize, enqueue 50 simple Queueable jobs that do nothing.
4. Run the class via System.enqueueJob in anonymous Apex and check that all 50 jobs are queued successfully.
5. Add a 51st enqueue in the same finalize method and re‑run; you should see a LimitException in the logs.
6. Inspect the debug log for separate EXECUTION_STARTED/EXECUTION_FINISHED blocks around the finalize method to confirm a new transaction.
