Vahid Hashemian commented on KAFKA-3818: ---------------------------------------- [~granthenke] I believe the problem you mentioned still exists in round robin assignor. Improving this assignor from the fairness point of view would very likely involve additional overhead (KIP-49 implementation is an example that brings fairness at the expense of a more complex solution). Going back to [~hachikuji]'s comment earlier, is this additional overhead accepted for a default assignment strategy? > Change Mirror Maker default assignment strategy to round robin > -------------------------------------------------------------- > > Key: KAFKA-3818 > URL: https://issues.apache.org/jira/browse/KAFKA-3818 > Project: Kafka > Issue Type: Bug > Reporter: Jason Gustafson > Assignee: Vahid Hashemian > > It might make more sense to use round robin assignment by default for MM > since it gives a better balance between the instances, in particular when the > number of MM instances exceeds the typical number of partitions per topic. > There doesn't seem to be any need to keep range assignment since > copartitioning is not an issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
