> Key: CASSANDRA-11370
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11370
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Paulo Motta
> Priority: Minor
> Labels: lhf
>
> After CASSANDRA-8004 we still display sstables in each level on nodetool tablestats as if we had a single compaction strategy, while we have one strategy for repaired and another for unrepaired data.
> We should split display into repaired and unrepaired set, so this:
> SSTables in each level: [2, 20/10, 15, 0, 0, 0, 0, 0, 0]
> Would become:
> SSTables in each level (repaired): [1, 10, 0, 0, 0, 0, 0, 0, 0]
> SSTables in each level (unrepaired): [1, 10, 15, 0, 0, 0, 0, 0, 0]
