Can you please do some benchmarks against MySQL and PostgreSQL? The vast majority of your prospective customers will be using these two instead of RocksDB or MongoDB.
We do not have any benchmark against PostgreSQL though. It is not in our plans to adapt our storage engine to PostgreSQL, so we're not comparing it against it, but the gains are just as significative.
I hope that answer your questions, and feel free to reach us at business@terark.com
