Vincent Mallet created CASSANDRA-6756: -----------------------------------------
Summary: Provide option to avoid loading orphan SSTables on startup Key: CASSANDRA-6756 URL: https://issues.apache.org/jira/browse/CASSANDRA-6756 Project: Cassandra Issue Type: Improvement Components: Core Reporter: Vincent Mallet Fix For: 1.2.16 When Cassandra starts up, it enumerates all SSTables on disk for a known column family and proceeds to loading all of them, even those that were left behind before the restart because of a problem of some sort. This can lead to "data gain" (resurrected data) which is just as bad as data loss. The ask is to provide a yaml config option which would allow one to turn that behavior off by default so a cassandra cluster would be immune to data gain when nodes get restarted (at least with Leveled where Cassandra keeps track of SSTables). This is sort of a follow-up to CASSANDRA-6503 (fixed in 1.2.14). We're just extremely nervous that orphan SSTables could appear because of some other potential problem somewhere else and cause zombie data on a random reboot. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
