-----------------------------------

Presumption was that we'd not get a partial result when we setBatch?
{quote}
We do return 'partial' results when we setBatch...
I guess at the time when the batch feature was introduced we had not introduced
the 'partial' flag yet. And the behavior is kept till now.
> 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.
