Alexey Goncharuk commented on IGNITE-2508:
------------------------------------------
Vladimir,
Changes look ok to me. I do not think that caching a set of UUIDs can
significantly increase memory footprint. As for the other potential places,
nothing pops into my head right away. I will create a ticket if I remember
something.
> GridDhtPartitionTopologyImpl#nodes(int, AffinityTopologyVersion) call are too
> costly.
