          Issue Type: Improvement
            Reporter: Vladislav Pyatkov


In some cases when we starts multiple caches (over 2K caches), we can to got a stop on exchange when new node joining to the cluster.

Coordinator-node wait to receive a single message from all other nodes, but last node (which want to joining to the cluster) stopped on starting caches:

that inhibits cluster exchange process, until all caches started on the last node.

 

We should to start caches in parallel threads or exclude the action from exchange init process.
