createIndexes Builds one or more indexes on a collection. Tip In mongosh, this command can also be run through the db.collection.createIndex() and db.collection.createIndexes() helper methods. Helper methods are
db.adminCommand({currentOp: true,$or:[{op:"command","command.createIndexes":{$exists:true}},{op:"none","msg":/^Index Build/}]}) 返回如下图所示,msg字段指明当前创建索引的进度,locks字段代表该操作的锁类型。更多锁说明信息,请参见MongoDB 官网。

MongoDB使用createIndex()方法来创建索引 注意:在 3.0.0 版本前创建索引方法为db.collection.ensureIndex(),之后的版本使用了db.collection.createIndex()方法,ensureIndex()还能用,但只是createIndex()的别名。 createIndex()方法基本语法格式如下所示: db.collection.createIndex(keys, options) ...
