Currently, I need to integrate MySQL client into SQLE as SQLE's client. And then, we just need design/implement a translation layer to transfer MySQL protocol into SQLE engine part (KV+ internal exactly).
Mysql-Proxy could solve this problem but it is complex to be only a MySQL server. Therefore, I remoduled MySQL-proxy to be more simple and easy to use and understand. See source codes https://github.com/HarryWei/lsqls for details.
