> Issue Type: Improvement
> Components: cache, general

> Fix For: 2.2

>
> There is an issue that has been in Ignite long ago and with the growing
> community and growing cluster sizes, it becomes more tangible.
> When a bunch of nodes leave or join cluster, we generate a separate discovery
> event for each node, and each discovery event generates a partition map
> exchange.
> The first idea that came to my mind was to coalesce the partition map
> exchanges, but this is extremely difficult to implement on unstable topology.
> Instead, we can introduce NODES_JOINED / NODES_FAILED events and batch
> multiple events on discovery level when possible. In this case, very few
> extra partition map exchanges are possible.
