> Current approach uses thread local ByteBuffer to write data while dumping caches.
> This can lead to memory overhead when only some threads from pool modifies data (call writeChanged) and for each thread separate ByteBuffer allocated. 
> We have PooledAllocator that can provide ability to reduce memory overhead.
> Need to study if it can be used in this case.
