Marcus Eriksson updated CASSANDRA-15462: ---------------------------------------- Reviewers: Marcus Eriksson > Purgable tombstones can cause false positives in repaired data tracking > ----------------------------------------------------------------------- > > Key: CASSANDRA-15462 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15462 > Project: Cassandra > Issue Type: Bug > Components: Observability/Metrics > Reporter: Sam Tunnicliffe > Assignee: Sam Tunnicliffe > Priority: Normal > Fix For: 4.0-beta > > > Calculating the repaired data digest on the read path (for the purposes of > detecting mismatches in the repaired data across replicas) is done before > purging any tombstones due to gcgs or last repaired time. This causes false > positives when repaired sstables include GC-able tombstones on some replicas > but not others. > Validation compactions do purge tombstones so it's perfectly possible for > sstables to mismatch in this way without causing any streaming during repair. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
