We have did the kafka cluster migration from source kafka cluster to target kafka cluster using MirrorMaker 2.5.1 in distributed mode using kafka connect cluster. We see noticeable difference incoming messages rate per sec on source and target. We also analyze that on kafka connect producer has less output rate compared to consuming rate of consumer.Details are given below. Do you suspect the message loss from kafka connect worker ?. We have seen the offsetsync topic the snapshots and data rate is quite well. Any help will be appreciated.
Kafka connect Consumer enter image description here <https://i.stack.imgur.com/YQGga.png>. kafka connect Producer enter image description here <https://i.stack.imgur.com/asp4t.png> source kafka:enter image description here <https://i.stack.imgur.com/JrKmK.png> target kafka: enter image description here <https://i.stack.imgur.com/Umtx7.png> We notices Mirror maker tasks and workers has no issues. We have three connect worker nodes only one connect node has this producer & consumer difference. As we don't have logs any insight will help to investigate the issue. Kafka MM Source connector producer and consumer uses default config only.
