Edoardo Comar commented on KAFKA-2273:
--------------------------------------
Working on this with [~vahid] - propagating the overall global assignment
solution of every consumer to every consumers in a group
by using the userdata field in the
org.apache.kafka.clients.consumer.internals.PartitionAssignor.Assignment.
This way, even if the leader dies, any other consumer on becoming the leader
has access to the last computed assignment for everyone.
> Add rebalance with a minimal number of reassignments to server-defined
> strategy list

> Add a new partitions.assignment.strategy to the server-defined list that will
> do reassignments based on moving as few partitions as possible. This should
> be a quite common reassignment strategy especially for the cases where the
> consumer has to maintain state, either in memory, or on disk.
