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。

port: 27017
database: mongodemo
效果:
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。
