> Now our read/write path allocate ByteBuffer from the ByteBufferPool, but we
> need consider the minSizeForReservoirUse for better utilization, those
> allocate/free api are some static methods, not so good to use.
> For HBASE-21879, we need an universal ByteBuffer allocator to manage all the
> ByteBuffers through the entire read path, so create this issue.
> Will upload a patch to abstract an ByteBufAllocator.
