Subject [jira] [Created] (CASSANDRA-14513) Reverse order queries in presence of range tombstones may cause permanent data loss
Date Tue, 12 Jun 2018 15:02:00 GMT
Sam Tunnicliffe created CASSANDRA-14513:
-------------------------------------------

             Summary: Reverse order queries in presence of range tombstones may cause permanent
data loss
                 Key: CASSANDRA-14513
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14513
             Project: Cassandra
          Issue Type: Bug
          Components: Core, CQL, Local Write-Read Paths
            Reporter: Sam Tunnicliffe


Slice queries in descending sort order can create oversized artificial range tombstones. At
CL > ONE, read repair can propagate these tombstones to all replicas, wiping out vast data
ranges that they mistakenly cover.
