Vladislav Pyatkov updated IGNITE-7703:
--------------------------------------
    Description: 
Ignite allows to create (and/or get) caches in batch, but not allows to do get 
without create.

In some cases need to start particular subset of all cluster caches, but if 
calls this one by one:

_org.apache.ignite.Ignite#cache_

we have a risk to overload discovery layer by messages of 
_DynamicCacheChangeRequest_.

 

Will be better to add a specific method for gets of caches in batch.

_org.apache.ignite.Ignite#caches_
