Summary: New MirrorMaker option partition.to.partition
Key: KAFKA-8226
URL: https://issues.apache.org/jira/browse/KAFKA-8226
Project: Kafka
Issue Type: Improvement
Components: core
Reporter: Ernestas Vaiciukevičius
Currently when MirrorMaker moves data between topics with records with null
keys - it shuffles records between destination topic's partitions. Sometimes
it's desirable trying to preserve the original partition.
Related PR adds new command line option to do that:
When partition.to.partition=true MirrorMaker retains the partition number when
mirroring records even without the keys.
When using this option - source and destination topics are assumed to have the
same number of partitions.
