Brandon Williams commented on CASSANDRA-5366: --------------------------------------------- I see, that makes sense. We'll need a 'nodetool recompactall' or something similar to replace it, since occasionally upgradesstables has been used to do this for various reasons. > UpgradeSSTables Optimisation > ---------------------------- > > Key: CASSANDRA-5366 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5366 > Project: Cassandra > Issue Type: Improvement > Reporter: Brooke Bryan > > Currently, if you run upgradesstables, cassandra will run through every > single SSTable within the scope of the request. Where we have some large > tables, an upgrade on a single sstable can take hours, even if its already > sat on the same version. > After upgrading to a new cassandra version, it would be ideal to be able to > upgrade only sstables not sat in the latest version, as it seems like it just > needs to do a massive amount of disk IO, with nothing being achieved at the > end of it. > Maybe its worth putting an option onto the nodetool command, or creating a > new command for this type of upgrade -- This message is automatically generated by JIRA.
