背景：
xdb其实足够完美了，现在回想一下，觉得有点复杂，我们不应该绑定语言，最好有自己的架构思路。
七号堡垒作为成功的商业项目，告诉我：其实数据是多读少写的，有修改的时候直接改库也是没问题的，这样子有个好处就是rpc获取到的数据足够的准确。
跨服这块结合redis，我们可以轻松获取其它服的数据。
华珺的Player数据管理思路，将所有的数据都存放Role上，这样子获取是十分的简单。
因此，我决定写一个简单而又足够上线的框架，思路：
技术栈： SpringBoot+netty+mongo+pb 。
是按照模块划分成多线程的，也就是: 尽量单进程多线程去完成任务。

总结：
可见游戏服使用mongo是十分合适的，轻松面对复杂的数据结构，并且和java集合框架完美结合。
其实，修改数据这块，我们可以登录时是: 同步记载，保存时，可以异步。
