>
> In the present implementation, the available buffer is divided into blocks
> (specified in the constructor for pipeline sort). and a linked list of these
> block byte buffers is maintained.
> A span is created out of the buffers.
> The present logic, doesnot handle scenario where a single key-value pair size
> doesnot fit into any of the blocks.
> example if 1mb total memory is divided into 4 blocks, (256 kb each),
> if a single KV pair is greater than the blocksize(~ignoring meta data size),
> then it fails with buffer exceptions.
