---------------------------------------------
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].
