Stephen Powis created KAFKA-3333: ------------------------------------ Summary: Client Partitioner - Round Robin Key: KAFKA-3333 URL: https://issues.apache.org/jira/browse/KAFKA-3333 Project: Kafka Issue Type: New Feature Components: clients Reporter: Stephen Powis
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
