ramkrishna.s.vasudevan commented on HBASE-13387:
------------------------------------------------
Agree that we will have two code paths with hasArray. But for a Cell that we
create from the Hfile blocks at the reader level could have an offheap BB or an
onheap BB from which we could create a cell.
Now for all the underlying comparisons in the comparator we need to know if the
Cell is backed by BB or byte[]. We need APIs in cells to deal with BBs anyway
because current APIs has byte[] only. Now in the comparators how we will do the
comparison without knowing what the cell is made up of? May be am not getting
your point here. Sorry about that.

> 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 'ServerCell' in which we can add new
> buffer based getter APIs, hasArray API etc. We will keep this interface
> @InterfaceAudience.Private
> Also we have to change the timestamp and seqId on Cells in server side. We
> have added new interfaces SettableSequenceId, SettableTimestamp for this. Now
> if we can add a ServerCell we can add the setter APIs there.
