Command在Mongodb中是一类特殊操作,它提供了强大的管理及各项操作(比如建库,索引,删除集合等)。可以说通过Command可以完成几乎所有想做的事情。同时Mongodb开发者在Command上又做了非常清晰体系架构和设计,便于管理和高效执行各种类型的Command。 Command体系 为了对其中大部分command对一个大致的了解,我们可以用下面指令来...
DbMessage._msg成员为DbMessage 类型,DbMessage的_nsStart和_theEnd成员分别记录完整mongodb报文的起始地址和结束地址,通过这两个指针就可以获取一个完整mongodb报文的全部内容,包括header和body。 注意:DbMessage是早期mongodb版本(version<3.6)中用于报文body解析封装的类,这些类针对opCode=[dbUpdate, dbDelete]这个区...

Although you get MongoDB Shell with MongoDB server installation as a binary, you can download and install MongoDB Shell separately too. MongoDB Shell can be used to perform CRUD (create, read, update, and delete) operations, as well as administrative tasks via CLI. The newer version, mongo...
Example #4 MongoDB::command() "textSearch"实例 在MongoDB 2.4以上版本中使用全文检索功能(之前的版本不支持全文检索)。 <?php$m = new MongoClient();$d = $m->demo;$c = $d->planets;$c->insert(array("name" => "Mercury", "desc" => "Mercury is the smallest and closest to the Sun...
mongod操作命令:客户端可以通过mongod复制集和cfg server访问集群的相关命令。 mongodb集群内部命令:mongos、mongod、mongo-cfg集群实例之间交互的命令。 Command命令处理模块核心代码实现如下: 《command命令处理模块源码实现》相关文章重点分析命令处理模块核心代码实现,也就是上面截图中的命令处理源码文件实现。
