无法对时间序列集合执行非多重更新

Question

您好，我正在使用新的 Timeseries mongodb 集合。我的 mongodb 版本是 5.0.6。我正在关注 this 教程。我创建了一个这样的集合。

   db.createCollection("ticker", {
     timeseries: {
        timeField: "time",
        metaField: "metadata",
    },
});

我是这样插入示例文档的。

db.ticker.insertOne({
 time: ISODate("20210101T01:00:00"),
 symbol: "BTC-USD",
 price: 34114.1145,
 metadata: { a: ""}
});

当我尝试更新元数据字段时出现上述错误。如前所述，here 是您只能更新 metaField 的限制，但它仍然给出上述错误。这是更新代码

db.ticker.update({ "metadata.a": "a" }, { $set: { "metadata.d": "a" } })

write failed with error: {
    "nMatched" : 0,
    "nUpserted" : 0,
    "nModified" : 0,
    "writeError" : {
        "code" : 72,
        "errmsg" : "Cannot perform a non-multi update on a time-series collection"
    }
}

我做错了什么需要帮助。

尝试添加 { multi: true } 配置。

如果您勾选 the docs，更新 time-series 集合仍然存在一些限制。

Update commands must meet the following requirements:

The query may only match on metaField field values.

The update command may only modify the metaField field value.

The update must be performed with an update document that contains only update operator expressions.

The update command may not limit the number of documents to be updated. You must use an update command with multi: true or the updateMany() method.

The update command may not set upsert: true.
