[Feature] Maintain heartbeat between proxy and broker #9725
Description
Is Your Feature Request Related to a Problem?
When the cluster traffic is not high or the cluster size is large enough, the proxy and broker only maintain the connection by sending messages or other information. There is a chance that the connection will be established only when sending or consuming. Because the broker will close the idle connection after 120 seconds.
A logic similar to the previous client is needed to send heartbeats regularly.
