> Project: HBase
> Issue Type: Improvement
> Reporter: Anoop Sam John
> Assignee: Anoop Sam John

> 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.
