> Key: PHOENIX-6068
> URL: https://issues.apache.org/jira/browse/PHOENIX-6068
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.0.0, 4.14.3
> Reporter: Kadir OZDEMIR
> Assignee: Kadir OZDEMIR
> Priority: Major
> Fix For: 4.16.0
>
>
> Phoenix uses HBase PageFilter to limit the number of rows returned by scans.
> If a scanned index row is unverified, GlobalIndexChecker repairs this rows.
> This repair operation leads to either skipping the unverified row or scanning
> its repaired version. Every scanned row including unverified rows are counted
> by the page filter. Since unverified rows are counted but not returned for
> the query, the actual number of rows returned for a LIMIT query becomes less
> than the set limit (i.e., page size) for the query.
