Create a nodetool upgrade_sstables to avoid using scrubs for tasks it wasn't intended to. -----------------------------------------------------------------------------------------
Key: CASSANDRA-3406 URL: https://issues.apache.org/jira/browse/CASSANDRA-3406 Project: Cassandra Issue Type: New Feature Components: Core Affects Versions: 1.0.0 Reporter: Sylvain Lebresne Assignee: Sylvain Lebresne Priority: Trivial Fix For: 1.0.2 Scrub was intended to check a data file is not corrupted and to try to correct some form of corruption and discard the data when it can't repair. But we are now using it also for: * major upgrade, to have sstable in the new data format for streaming sake (that one could be "fixed" independently by supporting old format during streaming) * to force the compaction of existing sstables after changing the compression algorithm We should probably provide a separate tool/command for those two last tasks since: * we could have a better name, like upgrade_sstables or rewrite_sstables for that operation * we could avoid the automatic snapshot that scrub does (and is not expected by users for those operations) * make it slightly quicker/simpler by avoiding the corruption detection code -- This message is automatically generated by JIRA.
