> Key: KAFKA-1215
> URL: https://issues.apache.org/jira/browse/KAFKA-1215
> Project: Kafka
> Issue Type: Improvement
> Components: replication
> Affects Versions: 0.8.0
> Reporter: Joris Van Remoortere
> Assignee: Jun Rao
> Fix For: 0.8.2
>
> Attachments: rack_aware_replica_assignment_v1.patch,
> rack_aware_replica_assignment_v2.patch
>
>
> Adding a rack-id to kafka config. This rack-id can be used during replica
> assignment by using the max-rack-replication argument in the admin scripts
> (create topic, etc.). By default the original replication assignment
> algorithm is used because max-rack-replication defaults to -1.
> max-rack-replication > -1 is not honored if you are doing manual replica
> assignment (preffered).
> If this looks good I can add some test cases specific to the rack-aware
> assignment.
> I can also port this to trunk. We are currently running 0.8.0 in production
> and need this, so i wrote the patch against that.
