We tried to upgrade the Kafka clients dependency from 0.8.2.1 to 0.10.0.0. As I understand, the producer client doesn't have major changes in 0.10, so we kept the same producer config in the upgrade:
retries 3 retry.backoff.ms 5000 timeout.ms 10000 block.on.buffer.full false linger.ms 5000 metadata.fetch.timeout.ms 30000 However, after the upgrade, the avg producer request latency increased by 5×, from a few hundreds milliseconds to 2-3 seconds. Anyone has seen this issue? Is there any change in 0.9/0.10 that would cause this? Thanks! -- Yifan
