Pavel Pereslegin updated IGNITE-7823:
-------------------------------------
    Description: 
Existing collocated version of {{IgniteSet}} datastructure is good enough for 
small sets.
For big sets it's too expensive to maintain redundant onheap data copies. Thus 
it would be better to use separate cache for non collocated {{IgniteSet}} 
version. The difference between these two kinds of sets should be properly 
documented afterwards. 

  was:Existing {{IgniteSet}} datastructure is good enough for small sets. For 
big sets it's too expensive to maintain redundant onheap data copies. Thus we'd 
better to add new {{IgniteCache::asSet}} method returning set adapter to 
existing cache. The difference between these two kinds of sets should be 
properly documented afterwards.
