Andrey,
IGNITE-4554 is about compressed bit sets, not standart bit sets.
Currently I'm implementing data structure based on [1]
It should efficiently handle sparse bit sets.

Hi Igor,
My C++ experience is based only on error code methods. This is why I
thought that exceptions based approach is unrelated to C++ at all.
I do remember we discussed all the pros and cons of these ways before.
Could you find that old discussion and share it here? I'm on a mobile now,
not ea
I'd suggest to have a single abstract class `Partitions` with protected
constructor and static factory method. This will allow to add different
optimized for any particular case implementations transparently.

Hi Guys
Alexei Scherbakov report a ticket few time ago [1]. The solution look
promissing.
Alexei, you wrote that this can save some memory. More over replacing
linked Set structure to array based bit-set
can give a speed-up due to array based structures are cache friendly.
But one thing is not c
BTW, I still need SQL queries part review.
