>
> RocksDB can expose some relatively useful figures via its 'getProperty' API.
> Some of them are documented on the
> [FAQs|https://github.com/facebook/rocksdb/wiki/RocksDB-FAQ] (eg.
> {{rocksdb.estimate-num-keys}} or {{rocksdb.estimate-live-data-size}}).
> It would be nice to be able to expose these via Samza metrics.
> There isn't a documented list of all the properties, but they're all visible
> in the source
> [here|https://github.com/facebook/rocksdb/blob/master/db/internal_stats.cc#L190].
