# Partitioner

Tooz provides a partitioner object based on its consistent hash ring implementation. It can be used to map Python objects to one or several nodes. The partitioner object automatically keeps track of nodes joining and leaving the group, so the rebalancing is managed.

    from tooz import coordination

    coordinator = coordination.get_coordinator('zake://', b'host-1')
    coordinator.start()
    partitioner = coordinator.join_partitioned_group("group1")

    # Returns {'host-1'}
    member = partitioner.members_for_object(object())

    coordinator.leave_partitioned_group(partitioner)
    coordinator.stop()
