Hi,
I have used YCSB to test the performance of mongo when storage engine is RocksDB and WiredTiger. the read/write ratio is 1/9 and the recordcount is 5000000. But I found the performance of rocksdb and wiredtiger seems no big difference.. I know that rocksdb is suitable for the scene writing much more than reading. But the result compared with wiredtiger seems not. I found the test results from github: https://github.com/wiredtiger/wiredtiger/wiki/YCSB-Mapkeeper-benchmark
So I want to know the purpose of mongodb supporting rocksdb. And the suitable scene for Rocksdb??

Thanks advance.
