Phil Yang commented on HBASE-17599:
-----------------------------------
And we should do some work at server to judge if a Cell is the last one of this
row or not. Now we can only say it must be the last or maybe not be the last,
because when some limit reached we just return what we read. This work is not
easy because we may have filter or read some of qualifiers.
> Also set the partial flag of Result to true if we reach the batch limit

> For now if we set scan.allowPartial(true), the partial result returned will
> have the partial flag set to true. But for scan.setBatch(xx), the partial
> result returned will not be marked as partial.
> This is an Incompatible change, indeed. But I do not think it will introduce
> any issues as we just provide more informations to client. The old partial
> flag for batched scan is always false so I do not think anyone can make use
> of it.
> This is very important for the limited scan to support partial results from
> server. If we get a Result which partial flag is false then we know we get
> the whole row. Otherwise we need to fetch one more row to see if the row key
> is changed which causes the logic to be more complicated.
