> Ignite cluster performs distributed partition map exchange when any server
> node leaves or joins the topology.
> Distributed PME blocks all updates and may take a long time. If all
> partitions are assigned according to the baseline topology and server node
> leaves, there's no actual need to perform distributed PME: every cluster node
> is able to recalculate new affinity assigments and partition states locally.
> If we'll implement such lightweight PME and handle mapping and lock requests
> on new topology version correctly, updates won't be stopped (except updates
> of partitions that lost their primary copy).
