MySQL-创建查询优化器附加组件

My question quite a general one. 我的问题很笼统。

I have to create a prototype of a query optimizer for mySQL, that works instead of standard one, or complements it. 我必须为mySQL创建一个查询优化器的原型，该原型可以代替标准的或可以对其进行补充。 It doesn't have to be very complicated, at the beginning. 在一开始时，它不必很复杂。 But is there a way of turning off the standard optimizer, so that I can check the way how mine works? 但是有没有办法关闭标准优化器，以便我可以检查我的工作方式？ And what language is the best for writing such an add-on? 哪种语言最适合编写此类插件？
