Phil Yang commented on HBASE-15484:
-----------------------------------
And I am not sure if the "paging" works if users don't want to limit the
time/size but want to display a limited number of cells to a upper level,
because the scanner is stateful and we must handle all results before the
scanner closed. It is a continuous flow for the whole Scan, we may have to deal
with all Cells in fact? I filed a issue, HBASE-15576 (sorry I have some higher
priority work so this issue has not any progress..), we can pass a Cell with
cf/cq/mvcc to server so we can "page" more powerfully.
> Correct the semantic of batch and partial

> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.2.0, 1.1.3
> Reporter: Phil Yang
> Assignee: Phil Yang
> Fix For: 2.0.0
>
> Attachments: HBASE-15484-v1.patch, HBASE-15484-v2.patch,

>
> Follow-up to HBASE-15325, as discussed, the meaning of setBatch and
> setAllowPartialResults should not be same. We should not regard setBatch as
> setAllowPartialResults.
> And isPartial should be define accurately.
> (Considering getBatch==MaxInt if we don't setBatch.) If
> result.rawcells.length<scan.getBatch && result is not the last part of this
> row, isPartial==true, otherwise isPartial == false. So if user don't
> setAllowPartialResults(true), isPartial should always be false.
