Hello Rahul,

I’m not quite certain which behaviour you wish to handle. Can you please elaborate on the scenario
you would like to cover?

Kind regards,
Finn

Actually, currently my subscriber bit slow to consume messages from the broker Or we can say publishing messages rate to a topic is high. So due to slow subscriber, attached clientId queue gets full and after that upcoming or old messages are getting dropped.

So how can we control/handle this behaviour ?

Hi Rahul,

thank you for clarifying. In order to reduce load on the subscribing side, you can
distribute load by using the shared subscription mechanism.
Your clients would subscribe to $share/group0/some/topic. Messages published to some/topic would then be split between all subscribers in group0. An explanation can be found in our blog post on shared subscriptions. I hope this helps.

Kind regards,
Finn
