> Key: CASSANDRA-9505
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9505
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jim Witschey
> Assignee: Sylvain Lebresne
> Fix For: 3.0.0 rc1
>
>
> It'd be helpful for us in TE if we could differentiate between data written
> in the sparse and dense formats as described
> [here|https://github.com/pcmanus/cassandra/blob/8099/guide_8099.md#storage-format-on-disk-and-on-wire].
> It'd help us to measure speed and space performance and to make sure the
> format is chosen correctly and consistently.
> I don't know if this would be best exposed through a JMX endpoint,
> {{sstablemetadata}}, or both, but those seem like the most obvious exposure
> points.
