Persistent Session for EMQX 5.1 and above

Hi Everyone,

I am currently using EMQX broker 5.0.22 for testing our IOT devices using docker-compose deployment and I thought of upgrading the broker to 5.1. Unfortunately I couldn’t find the Persistent Session topic in the Configuration manual. The EMQX broker (5.1) now does not persist the subscribers sessions if we restart the broker. I was wondering is the Persistent Session is now removed completely or is it now handled differently.

If it is handled differently where can I find the config parameters in the configuration manual.
