Summary: Optimize sticky assignor
Key: KAFKA-19478
URL: https://issues.apache.org/jira/browse/KAFKA-19478
Project: Kafka
Issue Type: Sub-task
Reporter: Lucas Brutschy
Assignee: Lucas Brutschy
The current assignor used in KIP-1071 is verbatim the assignor used on the
client-side. The assignor performance was not a big concern on the client-side,
and it seems some additional performance overhead has crept in during the
adaptation to the broker-side interfaces, so we expected this implementation to
be too slow for groups of non-trivial size. We need to optimize the assignor to
be able to efficiently run on the broker.
