How to properly update documents in MongoDB database?

Question

JavaScript

Hello. There was such a question, but first I’ll explain the essence. There is a site parser application and there is a mongoDb database where the parser sends objects with product data using the save () method. The problem is that most of the files in the database do not need to be updated, should they be filtered on the application side, i.e. first request all objects from the database, check them on the application side and then send unique ones to the database, or it’s more profitable to just send all objects using the save () method, and then let MongoDB figure out what it needs to update and what not to update.
