is it possible to modify ack deadline beyond 60 seconds

[Sachin Shetty]

Hi,

I am using the python client and running modify_ack_deadline every minute by 70 seconds. However after exactly 10 minutes, message is redelivered. It seems modify_ack_deadline does not work beyond 10 minutes, is there a way to keep renewing the dealine beyong 10 minutes? Our backend message processing could take hours.

Thanks
Sachin

Hi, Sachin,

Holding on to messages for hours for processing is an anti-pattern for Cloud Pub/Sub. With messages outstanding for that long, you run a large risk of messages being redelivered, which is what you are running into. You'd be better off writing the message to some kind of persistent storage once you receive it and then acking the message at that point, ensuring you then process any messages that are still in persistent storage. In this scenario, you may find that Pub/Sub is not well suited to your use case and that you are better off just writing to persistent storage directly instead of publishing a message.

Regards,

Kamal
