jiazhai opened a new pull request #5710: Add publish rate limit for each broker to avoid OOM URL: https://github.com/apache/pulsar/pull/5710 Fixes #5513 ### Motivation Through #3985, user could set the publish rate for each topic, but the topic number for each broker is not limited, so there is case that a lot of topics served in same broker, and if each topic send too many message, it will cause the messages not able to send to BookKeeper in time, and messages be hold in the direct memory of broker. And cause Broker out of direct memory. ### Modifications - add broker publish rate limit base on #3985, - add unit test. ### Verifying this change unit test passed.
