> Cleanup should skip sstables that don't contain data outside a nodes ranges
> ---------------------------------------------------------------------------

> Key: CASSANDRA-5722
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5722
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Nick Bailey
> Assignee: Tyler Hobbs
> Fix For: 2.0.1
>
>
> Right now cleanup is optimized to simply delete sstables that *only* contain
> data that doesn't belong on the node, for all other sstables though, it will
> read them, check each row, and write out new sstables.
> Cleanup could be optimized to look at an sstable and determine that all data
> within the sstable does belong on a node, and therefore skip re-writing that
> sstable. This would make cleanup essentially a noop in the case where all
> data on a node belongs on that node.
