This sounds a lot like mysql proxy (http://dev.mysql.com/doc/refman/5.7/en/mysql-proxy.html), which afaik is not recommended for production use.

I would very much like to know what the differences are (apart from the choice of programming language) and how stable this is.

Mixer is more like Atlas(https://github.com/Qihoo360/Atlas) or Cobar(https://github.com/alibaba/cobar).

You can define some rules to route sql to different MySQL servers, maybe it is the main difference.

Mixer can not be used in production now, I have been improving it and try to use it in my company first.

Sorry, only Chinese document. The authors may only focus Chinese MySQL users.

Btw, writing english document is very hard for many Chinese programmers, the same to me:)
