Can I get detailed metrics of the RocksDB that I have used in one of my streams ?

If you have configured your Structured Streaming query to use RocksDB as the state store, you can now get better visibility into the performance of RocksDB, with detailed metrics on get/put latencies, compaction latencies, cache hits, and so on. These metrics are available through the 

StreamingQueryProgress and StreamingQueryListener

 APIs for monitoring a streaming query.
