M. Manna updated KAFKA-3333:
----------------------------
Description:
** Please Look into KAFKA-7358 for the official description **
The
[DefaultPartitioner|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/producer/internals/DefaultPartitioner.java]
typically distributes using the hash of the keybytes, and falls back to round
robin if there is no key. But there is currently no way to do Round Robin
partitioning if you have keys on your messages without writing your own
partitioning implementation.
I think it'd be helpful to have an implementation of straight Round Robin
partitioning included with the library.
