> Improve anticompaction after incremental repair
> -----------------------------------------------
>
> Key: CASSANDRA-6851
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6851
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Marcus Eriksson
> Assignee: Russell Alexander Spitzer
> Priority: Minor
> Labels: compaction, lhf
> Fix For: 2.1.1
>
>
> After an incremental repair we iterate over all sstables and split them in
> two parts, one containing the repaired data and one the unrepaired. We could
> in theory double the number of sstables on a node.
> To avoid this we could make anticompaction also do a compaction, for example,
> if we are to anticompact 10 sstables, we could anticompact those to 2.
> Note that we need to avoid creating too big sstables though, if we
> anticompact all sstables on a node it would essentially be a major compaction.
