-------------------------------------------
Summary: Rack-Aware replica assignment option
Key: KAFKA-1226
URL: https://issues.apache.org/jira/browse/KAFKA-1226
Project: Kafka
Issue Type: Improvement
Components: replication
Affects Versions: 0.8.0, 0.8.1
Reporter: Joris Van Remoortere
Assignee: Neha Narkhede
Fix For: 0.8.0
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.
