-------------------------------------------
Summary: Validate range tombstones and clustering order on the
write path
Key: CASSANDRA-14858
URL: https://issues.apache.org/jira/browse/CASSANDRA-14858
Project: Cassandra
Issue Type: Bug
Reporter: Blake Eggleston
Assignee: Blake Eggleston
Some fuzz testing I've been doing uncovered some situations where invalid
tombstones could be written and/or unfiltereds could be written to sstables out
of clustering order. Both of these caused pretty severe database breakage.
Although cql statement logic should (in theory) prevent users from triggering
these bugs in normal use, it's possible there's an edge case somewhere that
could write data like this. We should add some validation in the lower levels
of the storage layer to protect it from bugs / malicious input from the higher
levels.
