[question] Is There a Message Acknowledgment Mechanism? Recommendations for Implementing Acknowledgment?

[perfgao]

Hello,
I am currently using Centrifugo for real-time messaging in our application, and I have a couple of questions regarding message acknowledgment:

Message Acknowledgment: Does Centrifugo have a built-in message acknowledgment mechanism? If so, could you please provide some details on how it works?

Implementing Acknowledgment: If Centrifugo does not support a built-in acknowledgment mechanism, do you have any recommendations or best practices for implementing message acknowledgment at the application level? For example, any suggested patterns for ensuring that messages are successfully received and processed by clients?

Hello @perfgao

There is no built-in ack support, check out FAQ: https://centrifugal.dev/docs/faq#how-can-i-know-a-message-is-delivered-to-a-client - so it's possible to implement the mechanism sending requests from the client to your backend - using HTTP, or maybe Centrifugo RPC proxy.

But the rest depends on your specific case. Since I am not aware of app specifics I can not provide any other useful advice at this point.

If you see that the ack mechanism should be somehow part of Centrifugo – need to look closer on exact problematic and how built-in implementation is better than suggested in FAQ.
