Description

RocksDB can expose some relatively useful figures via its 'getProperty' API. Some of them are documented on the FAQs (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.
