--------------------------------------
Summary: Read repair reduces the number of rows returned for LIMIT
queries
Key: PHOENIX-5969
URL: https://issues.apache.org/jira/browse/PHOENIX-5969
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.3, 5.0.0
Reporter: Kadir OZDEMIR
Assignee: Kadir OZDEMIR
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.
