@lhotari Thank you so much for your help! When I ran pressure tests with 1KB small messages, the performance was solid and stable—only partition imbalance occurred, with a TPS of around 250K. However, when consuming 500KB large messages, performance degrades after a few minutes, paired with severe partition consumption imbalance. The most critical issue is that the consumption rate metrics for partitions vanish entirely: neither pulsar-manager API queries nor the pulsar_rate_out metric returns any data (this affects all brokers). Other metrics appear normal, and no thread blockages were detected in the broker thread dumps. Additionally, no priority distinctions were configured for the consumers. -- This is an automated message from the Apache Git Service.
