如何在mongo中创建锁定/签出机制？

Question

我有多个访问同一mongodb的node.js实例，它们都在执行相同的任务。我想确保在保存时间没有运行相同的任务。是否有“最佳实践”方法来签出任务？

到目前为止，这是我所拥有的，但这不是最好的方法，因为我似乎仍在发送重复的消息。

我在做什么错？我该怎么做呢？

// Check if there is a locked message.
const cutoff = moment()
    .subtract(3, "minute")
    .toDate();
let message = await Message.findOneAndUpdate(
    {
        listingID: listing._id,
        messageRuleID: messageRule._id,
        reservationID: reservation._id,
        disable: {$ne: true}, // Message is not disabled
        messageSent: {$ne: true}, // Message is not sent
        $or: [
            {
                lockedAt: null // If the message is not locked (null)
            },
            {
                lockedAt: {$exists: false} // If the message is not locked (doesn't exist)
            },
            {
                lockedAt: {$lte: cutoff} // If it was locked more that 3 minutes ago
            }
        ]
    },
    {
        listingID: listing._id,
        messageRuleID: messageRule._id,
        reservationID: reservation._id,
        lockedAt: moment().toDate() // Check out the message with the current date
    },
    {upsert: true, new: true}
);
// If no message doc is returned, that means it's disabled, has already been sent or is being sent.
if (!message) {
    return;
}
