I would like to initiate the voting process for KIP-70 ( https://cwiki.apache.org/confluence/display/KAFKA/KIP-70%3A+Revise+Partition+Assignment+Semantics+on+New+Consumer%27s+Subscription+Change ).
The only issue that was discussed in the discussion thread is compatibility, but because it applies to an edge case, it is not expected to impact existing users. The proposal was shared with Spark and Storm users and no issue was raised by those communities. Thanks. Regards, --Vahid
