Anoop Sam John commented on HBASE-13387:
----------------------------------------
In the entire read path, Cell is changed to ServerCell.
You mean we have to do instance of check and do type casting in places like
CellComparators? This will be too ugly IMO. We will have to do it is so many
places. Change of Cell to ServerCell in args might be better IMHO.
> Add ServerCell an extension to Cell

> 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.
