ramkrishna.s.vasudevan commented on HBASE-10680:
------------------------------------------------
This was just to see if every where we could store as Cells and this means even
in the write path. Currently from KV we extract out the key part and was
storing it as a key byte[]. The key byte[] i mean the root level,
intermediate keys etc.
So for direct comparison with a cell and it's key part we had to extract the
key portion from the Cell and then do the compare (that is where the
KeyOnlyKeyValue) was introduced. I think for doing this we may have to change
the write path also which I think is not easily doable without changing the
format of the Hfile layouts. Can defer this for now and reopen when needed.

> While doing HBASE-10531 we can observe that most of the comparison happens
> between the key part of the KVs. If suppose we need to make use of Cells
> and get rid of Kv.getBuffer() then the Keys with which the comparison are
> done like the block keys, index keys etc should also be changed to Cells and
> internally do the comparison as cell. This issue would help to brain storm
> this and implement the feasible soln.
