Hi@akhtar,

If you already created multiple producers then use the bellow command according to your port no.

$ ./bin/kafka-console-consumer.sh --zookeeper localhost:2181 -topic topic-name --from-beginning

Thank You

First of all, Consumer is not thread safe. So before going to write multiple consumers please make this class as thread safe. After that, you can execute as multiple worker in multithreading environment using Executor Framework.
