jiazhai commented on issue #5513: Publish rate limit on broker to avoid OOM URL: https://github.com/apache/pulsar/issues/5513#issuecomment-549247676 Hi @rdhabalia @merlimat. Thanks for your concern. And thanks @rdhabalia for your great feature of #3985. Recently there is a user trying to use Pulsar along with Flink, and there is a significant amount of messages produced. They meet the OOM of direct memory very often. #3985 and the setting that Matteo mentioned may solve part of the issue, but the OOM in Broker may still exists. I thought we could leverage part of the change in #3985, and add another broker scope config to do the publish rate limiting.
