RocksDB is an amazing piece of engineering that deserve to be more known. It is battle tested. It does one job and does it well. I have used it in the past as a middleware database taking an average of 2-3k req/sec with over 400 GB of data stored. It works like a charm. If I had a single reproach to do to it, it would be around the instrumentation. It is not that straightforward to get proper metrics and reporting of the internals.
