After implementing the code provided below, I noticed that the performance tests indicate each request takes a second or longer to complete. My goal is to enhance this speed by at least 10 times. The bottleneck seems to be caused by the NOT operator resulting in a full scan of the data. Is there a more efficient way to execute the $not $in operation? Perhaps there is a different approach that can yield faster results. I experimented with using $lookup to join a temporary collection with the main one, but it turned out to be even slower as it involved creating a new collection, inserting data, running the $lookup query, and then deleting the temporary collection afterwards. I am curious if there is such a thing as a "negative" index that could improve performance.
const filter = {
state: "Live",
id: { $not: { $in: ids } },
"type": "Message",
};
const docs = await MyModel.find(filter, { _id: 0, __v: 0 })
.sort({ "live_date": -1 })
.lean();
}
