# MirrorMaker

MirrorMaker is a Kafka process that replicates data between Kafka clusters or Kafka-compatible data stores such as Warpstream. A video walkthrough can be found below:

You should tune your producer settings like we recommend [there](https://docs.warpstream.com/warpstream/kafka/configure-kafka-client/tuning-for-performance).

If you notice that producing data from the MirrorMaker is taking too much time for the throughput it tries to handle and encounters consumer group timeouts, then you can try the following:

* bump the `session.timeout.ms` to 2-5min
* increase the `max.poll.interval.ms` to 10min
* set `max.poll.records` to 100-300 (default is 500)
