Hi everyone, running with Kafka Streams 0.10.2.0, I see this every commit interval:
2017-02-28T21:27:16.659Z INFO <> [StreamThread-1] o.a.k.s.p.internals.StreamThread - stream-thread [StreamThread-1] Committing task StreamTask 1_31 2017-02-28T21:27:16.659Z INFO <> [StreamThread-1] o.a.k.s.p.internals.StreamThread - stream-thread [StreamThread-1] Committing task StreamTask 2_31 We have ~10 tasks in our topology, 4 topics, and 32 partitions per topic. This means every commit interval we log a few hundred lines of the above which is an order of magnitude chattier than anything else in the log during normal operations. Does anyone else find the chattiness of this message annoying? I would personally prefer something more like: # existing message is fine at TRACE level for diagnostics "TRACE o.a.k.s.p.i.StreamThread - Committing task StreamTask 1_31" # normal fast case, wrap them all up into one summary line "INFO o.a.k.s.p.i.StreamThreads - 64 stream tasks committed in 25ms" # some kind of threshold / messaging in case it doesn't complete quickly or logs an exception "ERROR o.a.k.s.p.i.StreamThread - StreamTask 1_32 did not commit in 100ms" Thoughts?
