原文 6 Rules of Thumb for MongoDB Schema Design: Part 2. By William Zola, Lead Technical Support Engineer at MongoDB. 如果你想让你的设计更酷,你可以让引用的 one 端和 many 端同时保存对方的引用。 在task文档对象中添加额外的 owner 引用可以很快的找到某个task的所有者,但是如果想将一个task分配给其他person就需要更新引用中的person和task这两个对象 熟悉关系数据库的童鞋会发现这样就没法保证操作的原子性。 通过在查询中使用投影参数 类似{ id:1} 的方式在不需要使用logmsgs数组的情况下避免获取整个mongodb对象,1000个日志信息带来的网络开销是很大的。 想学习更多可以点击 Thinking in Documents.
