[jira] [Created] (SAMZA-1461) Expose RocksDB properties as metrics

Janek Lasocki-Biczysko created SAMZA-1461:
---------------------------------------------

             Summary: Expose RocksDB properties as metrics
                 Key: SAMZA-1461
                 URL: https://issues.apache.org/jira/browse/SAMZA-1461
             Project: Samza
          Issue Type: Improvement
          Components: kv
            Reporter: Janek Lasocki-Biczysko


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].
