Ismael Juma resolved KAFKA-4313. -------------------------------- Resolution: Fixed Fix Version/s: 0.10.2.0 Issue resolved by pull request 2043 [https://github.com/apache/kafka/pull/2043] > ISRs may thrash when replication quota is enabled > ------------------------------------------------- > > Key: KAFKA-4313 > URL: https://issues.apache.org/jira/browse/KAFKA-4313 > Project: Kafka > Issue Type: Bug > Affects Versions: 0.10.1.0 > Reporter: Jun Rao > Assignee: Jun Rao > Fix For: 0.10.2.0, 0.10.1.1 > > > I created a high volume topic and a low volume topic, each with 1000 > partitions and 2 replicas on 2 brokers. I populated the high volume topic > with 4GB of data. Added a third broker and ran the rebalance tool with a > 2MB/sec replication quota. At some point, all replicas for the low volume > topic have been moved over and the new replicas are all in sync, but the high > volume replicas are still catching up. Then, I started slowly producing to > the low volume topic. Once I do that, I started seeing the low volume > partitions' ISR constantly expanding and shrinking. The observed ISR change > rate is ~ 6/sec. So, it does seem that ISR thrashing can happen. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
