Sergey Shelukhin updated HIVE-12597:
------------------------------------
Attachment: HIVE-12597.patch
The patch creates new interface for refcount management and offers 3 options -
old, where cache implements both cache and buffer manager interfaces,
buddy-allocator-only with no cache and simple management, and simple allocator
with simple refcounts.
It also moves a number of configs into the correct scope (i.e. allocator
configs are now named allocator config, and not cache configs).
> LLAP - allow using elevator without cache

> Elevator is currently tied up with cache due to the way the memory is
> allocated. We should allow using elevator with the cache disabled.
