      Description

      The correct fix for KAFKA-262 and other known issues with the current consumer rebalancing approach, is to get rid of the cache in the zookeeper consumer.
      The side-effect of that fix, though, is the large number of zookeeper notifications that will trigger a full rebalance operation on the consumer.

      Ideally, the zookeeper notifications can be batched and only one rebalance operation can be triggered for several such ZK notifications.
