GitHub user MayureshGharat opened a pull request:

    Handle Repartitioning of Streams

    Modified the Groupers to handle Repartitioning. This is an opt in feature and can be enabled
by setting the config : "auto.handle.repartition" to true.
    This patch assumes that we add a new interface in the groupers that provides access to
the previous mapping of tasks to SSPs.
    This assumes that the number of partitions are always increased by a factor of 2.
    This also assumes that the partitioning algorithm used by the producer is "hash(key) %
