Anoop Sam John commented on HBASE-13754:
----------------------------------------
We need reverse of CellOutputStream . It has
write(Cell cell)
What we need is mark a Cell such that it can write itself to an OS. So instead
an outside util get each component length and component bytes from Cell and
write them one after the other, the cell might go an optimized route.. (Just
like KeyValue used to do till now)
> Allow non KeyValue Cell types also to oswrite

> While making the cellblock for returning data to client, we have to write the
> cell data into an OutputStream. KeyValue has a static oswrite() method with
> which it can write data in one go. (KeyValue components are in a single
> byte[]). For other cell implementation, we will call getXXXLength() and
> getXXXArray() and write each component one after the other. This is not
> efficient as the KeyValue way. In fact other cell impls also may have one
> contigous byte[] backing for keys atleast. (See ClonedSeekerState) We can
> optimize for such Cells also.
