1、创建索引db.userInfo.ensureIndex({name: 1});db.userInfo.ensureIndex({name: 1, ts: -1}); 2、查询当前聚集集合所有索引db.userInfo.getIndexes(); 3、查看总索引记录大小db.userInfo.totalIndexSize(); 4、读取当前集合的所有index信息db.users.reIndex(); 5、删除指定索引db.users.dropIndex("name_1"...

MongoDB 分片是基于区域(range)的。所以一个集合(collection)中的所有的对象都被存放到一个块(chunk)中,默认块的大小是 64Mb。当数据容量超过64 Mb,才有可能实施一个迁移,只有当存在不止一个块的时候,才会有多个分片获取数据的选项。 问:更新一个正在被迁移的块(Chunk)上的文档时会发生什么? 更新操作会立即发...
