Anoop Sam John updated HBASE-13754:
-----------------------------------
Attachment: HBASE-13754.patch
This will be very much useful for the Offheap backed Cells.
Also pls see the method override in NoTagsKeyValue where we can avoid parsing
of keyLength and valueLength and some math.
KeyValue#oswrite(final KeyValue kv, final OutputStream out) was deprecated inn
0.98 itself and we can remove it for 2.0 I believe
> 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.
