Re: Kafka Mirror Maker 2

Hi Himanshu

Can u pls tell how to use MM2..

I am using Apache Kafka,in this normal mirror maker is only available..

Most of the people saying like to use MM2 but I didn't able to know where
to get that MM2.

Is it related to Apache or from some other Distributors?

Can u pls explain how to install that version
