Hi All, I'm doing smoke testing with my Kafka Streams app(V2.1.0). I noticed that below behaviors: 1) Out throughput of changelog topic could go up to 70mb/s while the in-traffic is around 10mb/s. 2) When traffic is bumpy, either due to producer/consumer throttle or some other reasons I'm still debugging, changelog topic out throughput could go up to 160mb/s while in-throughput is less than 1mb/s. And from the monitor tool, no messages are actually put into this topic.
Could anyone help me to understand how changelog topic works? Given it still has consumer lag and producer timeout issues(records expired(5min) since batch created), is it just the cluster bandwidth/capacity issue? Thanks, appreciate all the help!!
