mongodb命令以递归方式在所有文档中重命名键

Question

我有一个名为“ x”的密钥，并希望在它出现的所有文档中将其重命名为“ y”。

键可以出现在词典列表中，也可以出现在词典字典中，也可以位于平面词典中。

在所有情况下它都应该起作用。替换应类似于linux的“ sed”命令，该命令将替换显示的所有字符串。

我是mongodb的新手，请帮助我更换密钥。

                    }
            ]
    },
    {
            "_id" : ObjectId("5d142cefc796880001cf3321"),

            "_class" : "do_backup.model.DoBackup1",
            "backup_info" : [
                    {
                            "job_type" : "INSTANTLY1",
                            "filename" : "",
                            "filepath" : "",
                            "time_elapsed" : "1mins22sec",
                            "filesize" : "",
                            "remarks" : "Comm. Failure",
                            "status" : "Failure",
                            "timestamp" : NumberLong("1561603396001"),
                            "signature" : "NA"
                    }
            ]
    }

在一个小场景中，我想将键“状态”更改为“状态”。
