Paul Querna commented on CASSANDRA-1811:
----------------------------------------
An alternative would be to extend forceclean in jmx to allow you to specify
both the Keyspace and a CF, so that you could manually do specific CFs.
> Cleanup smallest CFs first
> --------------------------
>
> Key: CASSANDRA-1811
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1811
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Paul Querna
> Priority: Minor
>
> When running a cleanup, it would be an advantage to anti-compact the smallest
> SSTables first, so that free disk space is gradually increased, so that
> larger sstables later on are more likely to successfully anti-compact.
> In 0.6, currently Table.forceCleanup() just iterates the list of CFs in
> whatever order they come from tableMetadata.getColumnFamilies, which is just
> a keySet().
> The code should be changed to sort the CFs, smallest first.
