How to update collection entries in mongodb with different results?

Question

MongoDB

The question is how to update multiple documents in a collection, but with different (unique) values ​​for each document.
So far, in nodejs, I do it through map, do the calculation and save it back to the database.
SQL has triggers that could be done, but mongo doesn't have them, what other option is there besides map?

Answer 1

Unfortunately map is the only option. You can try to get out with the $inc and $mul operators
