@wenbingshen Do you have a chance to test with 2.8.1 ? That contains quite a few fixes, just to see if there's a difference. > producerRate: 880000000 I assume you are intentionally testing an overload situation? > After analyzing the pulsar broker heap dump, a large number of PendingAddOp instances have not been recycled or destroyed. That is probably expected if there's such a high load on the system. One possibility to protect from overload is to configure rate limiters on the system. However, it would be good if the Pulsar system would have backpressure (even without rate limiting configured) to prevent the system getting into a state where it breaks because of OOM. One such improvement suggestion is documented in #10439 . -- This is an automated message from the Apache Git Service.
