Anoop Sam John commented on HBASE-13387:
----------------------------------------
bq. but how about tests of the new methods added especially when backed by a
BBCell?
I will add.. We are not having an impl for this right now. Will create a test
impl and add tests. In fact our local branch is having tests. My bad.. I
forgot to get those into this patch.
bq.Should ByteBufferedCell be in hbase-server module? Can it be in the
RegionServer package? (It doesn't look like it given we look for it in
comparators. I suppose also BBCell doesn't have to have anything to do with
Server when in common module. Someone else might want to use it for some other
purpose?
I also wanted it to be in server and thought that way initially. But we do
need this ref in classes like CellComparator, CellUtil etc which has to be in
common module. As of now no need to expose it outside of RS. We have Private
InterfaceAudience for this class. Is this ok? We do have some other similar
classes also in common module where the class makes sense only in RS. (like
org.apache.hadoop.hbase.io.hfile package fully?)

> This came in btw the discussion abt the parent Jira and recently Stack added
> as a comment on the E2E patch on the parent Jira.
> The idea is to add a new Interface 'ByteBufferedCell' in which we can add
> new buffer based getter APIs and getters for position in components in BB.
> We will keep this interface @InterfaceAudience.Private. When the Cell is
> backed by a DBB, we can create an Object implementing this new interface.
> The Comparators has to be aware abt this new Cell extension and has to use
> the BB based APIs rather than getXXXArray(). Also give util APIs in CellUtil
> to abstract the checks for new Cell type. (Like matchingXXX APIs,
> getValueAs<type> APIs etc)
