Checkpoint

Use this node to hand off processing to a different queue — for example, to move a message from a high-throughput queue to a lower-priority one, or to isolate computationally expensive processing into a dedicated queue with its own rate limits and retry policy. Once the copy of the message is successfully enqueued, the original message is acknowledged.

1. The node receives an incoming message.
2. A copy of the incoming message is created and enqueued to the configured target queue.
3. Once the copy is successfully enqueued, the original incoming message is acknowledged.
4. If enqueueing fails, the original message is routed via the Failure connection without being acknowledged.
