> Ignite has many uses of data structures like Set<Integer>, IntArray etc.
> This is not most efficient way to represent integer sets. The best way is to use compressed bit sets. This should save a lot of heap space.
> We should optimize integer sets whenever possible.
> The most obvious place to start is GridAffinityAssignment.
