Mongodb bulkwrite updateOne基于数组最后一个元素中的日期

如何解决Mongodb bulkwrite updateOne基于数组最后一个元素中的日期

我试图根据数组中最后一个元素的日期使用Mongoose和MongoDB批量写入进行更新。

原始文档：

{
    "_id": {
        "$oid": "507f1f11bcf86cd799439011"
    },"company": "ABC","historical": [{
            "_id": {
                "$oid": "5e0af1c63b6122125c1b42cb"
            },"month": {
                "$date": "2015-12-01T05:00:00.000Z"
            },"data": [{
                    "date": {
                        "$date": "2015-12-14T05:00:00.000Z"
                    },"open": 11.6224,"high": 11.6224,"low": 10.5124,"close": 10.5124,"adjClose": 10.5124,"volume": 19100,"change": -1.11,"changePercent": -9.551,"vwap": 10.8824,"changeOverTime": -0.09551
                }
            ]
        }
    ],"dividend": [ {
            "date": {
                "$date": "2020-04-24T00:00:00.000Z"
            },"payout": 0.11
        },{
            "date": {
                "$date": "2020-07-24T00:00:00.000Z"
            },"payout": 0.11
        }
    ]
}

我有一个数据数组-arr（为简化起见，减少了元素）：

[{
        "data": {
            "date": "2020-10-23","payout": 0.12
        },"company": "ABC"
    },{
        "data": {
            "date": "2020-10-23","payout": 0.12,},"company": "DEF"
    }
]

如果“ dividend”日期中的最后一个索引早于数据数组中的日期，则我尝试运行bulkwrite并通过推入“ dividend”数组来更新匹配的文档。 尝试查询：

var ops = arr.map(function (info) {
        return {
          updateOne: {
            filter: {
              company: info.company,'dividend.1.date': { // how can I retrieve latest date without explicitly specifying the index?
                $lt: new Date(info.data.date)
              }
            },update: { $push: { dividend: info.data } }
          }
        };
      });

      collection.bulkWrite(ops,function (err,r) {
        // carry on with result
      });

所需结果文档：

{
        "_id": {
            "$oid": "507f1f11bcf86cd799439011"
        },"historical": [{
                "_id": {
                    "$oid": "5e0af1c63b6122125c1b42cb"
                },"month": {
                    "$date": "2015-12-01T05:00:00.000Z"
                },"data": [{
                        "date": {
                            "$date": "2015-12-14T05:00:00.000Z"
                        },"changeOverTime": -0.09551
                    }
                ]
            }
        ],"dividend": [ {
                "date": {
                    "$date": "2020-04-24T00:00:00.000Z"
                },"payout": 0.11
            },{
                "date": {
                    "$date": "2020-07-24T00:00:00.000Z"
                },{
                    "date": {
                        "$date": "2020-10-23T00:00:00.000Z"
                    },"payout": 0.12
                }
        ]
    }

由于数据数组可能会变得很大，所以我宁愿在一次单次往返数据库中进行操作，而不要使用多个更新。 Mongoose和MongoDB可以做到这一点吗？希望有人可以帮我解决这个问题。在此先感谢！
