Summary: Incremental Rebalance Protocol for Kafka Consumer
Key: KAFKA-8179
URL: https://issues.apache.org/jira/browse/KAFKA-8179
Project: Kafka
Issue Type: Improvement
Components: consumer
Reporter: Guozhang Wang
Assignee: Guozhang Wang
Recently Kafka community is promoting cooperative rebalancing to mitigate the
pain points in the stop-the-world rebalancing protocol. This ticket is created
to initiate that idea at the Kafka consumer client, which will be beneficial
for heavy-stateful consumers such as Kafka Streams applications.
In short, the scope of this ticket includes reducing unnecessary rebalance
latency due to heavy partition migration: i.e. partitions being revoked and
re-assigned. This would make the built-in consumer assignors (range,
round-robin etc) to be aware of previously assigned partitions and be sticky in
best-effort.
