Relates to: KIP-13: Quotas, KIP-74: Add Fetch Response Size Limit in Bytes

Mail Thread: here

Released: 0.10.1.0

Revision History

  • 10th Aug 2016: Switched from a delay-based approach, which uses dedicated throttled fetcher threads, to an inclusion-based approach, which puts throttled and unthrottled replicas in the same request/response
  • 25th Sept 2016: Split throttled replica list into two properties. One for leader side. One for follower side.
  • 30th Sept 2016: Split the quota property into two values, one for the leader and one for the follower. This adds consistency with the replicas property changed previously.

Amendments

 

While testing KIP-73, we found an issue described in https://issues.apache.org/jira/browse/KAFKA-4313. Basically, when there are mixed high-volume and low-volume partitions, when replication throttling is specified, ISRs for those low volume partitions could thrash. KAFKA-4313 fixes this issue by avoiding throttling those replicas in the throttled replica list that are already in sync. Those in-sync replicas traffic will still be accounted for the throttled traffic though.

Q&A

1. How should an admin set the throttle value when rebalancing partitions?
