Is it possible to NACK messages?

[Ory Band]

Let's say I have a Pub/Sub subscription with 10 min deadline.

If I pull 5 messages, and 3 of them failed, is there a way to return them back into the queue (NACKing these messages) instead of having to wait for their deadline timeout?

Yes, you can call ModifyAckDeadline with a deadline of 0 seconds, and this will cause them to be NACKed.

Thanks,

Max

Hi, Ory,

As Max mentions, you would want to set the ack deadline to 0. This can be done in several ways. If you are using the client library, they tend to offer a way to nack directly. For example, the Java library provides the the nack method and the Go library allows you to call Done on a message with ack set to false. If you are using the RPC API or REST API directly, you should call ModifyAckDeadline with a deadline of 0 for the messages (RPC API, REST API).

Regards,

Kamal
