This is a little unsettling.

Yeah for end user this is not useful. Let me move this comment to another place.

Do you want to change the ScannerContext method partialResultFormed to match the above?
{quote}
Let me do it.

> 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.
