I contributed the original RocksDB code to YCSB, however as YCSB is in Java, it uses the RocksJava API.

The JNI interface has some overhead, so the results with RocksJava will be less than those of using RocksDB from C or C++. If you want C or C++ then @jay-zhuang's suggestion is likely the way to go. Otherwise if you want Java you can use https://github.com/brianfrankcooper/YCSB/tree/master/rocksdb
