Sergey Shelukhin updated HIVE-16233:
------------------------------------
Attachment: HIVE-16233.WIP.patch
Updated patch. Concurrency test now passes the concurrency part (incl. with
100s of iters), but forgets some parts of memory making the final verification
fail. Need to fix that (marked with a comment), consider a couple additional
optimizations, and removing one optimization :), and then clean up.

> We were initially planning to write a different allocator with compaction,
> but now we are stuck with buddyallocator.
> There are two approaches - compaction on top of buddy allocator (should be
> fairly simple actually, aside from indirection... luckily for the latter, we
> can take the buffer out in most places and we can reuse the existing
> locking-to-prevent-eviction mechanism to also prevent reallocation); or
> writing a better allocator. Probably the former is preferred, need to think
> about the latter.
