> Here 1st we write KVs (Cells) into a buffer and then passed to DBE encoder. Encoder again reads kvs one by one from the buffer and encodes and creates a new buffer.
> There is no need to have this model now. Previously we had option of no encode in disk and encode only in cache. At that time the read buffer from a HFile block was passed to this and encodes.
> So encode cell by cell can be done now. Making this change will need us to have a NoOp DBE impl which just do the write of a cell as it is with out any encoding.
