-------------------------------------------
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.
