I have an application that runs as multiple instances (pods on Kubernetes).

This application consumes messages from the queue with prefetch 1 and ack back after It finishes the process.

I have a function that must run from only one instance at a time. But the queue tries to send the next message to others instance consumers.

Is there anyways to block other consumers to not receive a message or block a queue to not send a message before ack?

Thanks you very much
