------------------------------------------------
bq.The model should not be such that Key only makes sense in case where row is
contiguous with column family and qualifier, etc.
Ok. So you mean make all Cell have a Key interface? I can come up with a patch
where Key interface is implemented in every cell and not make Cell extend Key.
bq.Streamable should be done with Codec?
Yes. But there is some relation between this Streamable and Key. Streambale
deals with both keys and values but Key is talking only about the key part.

> Introduce an interface called Key and allow Cell implementations to implement
> this Key interface for cases like KeyValue, OffheapKeyValue and DBE cells
> (Except prefix tree) so that we can avoid copies when we deal with only Cells
> in case of block index creations (like ROOT, Bloom etc). Helps in reduction
> of garbage also.
