stack commented on HBASE-13387:
-------------------------------
Lets see how far we get w/ BBC as the name of the Interface. As you say, the
Sequence Interface is write-time only. If we end up adding more features, we
might want to just put them all in a ServerCell bucket.
On the exception throwing, we'd fail fast when we go the wrong route and we
expose all the places where an unintended copy might be happening. That I like.
May be untenable though. Lets see...

> 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)
