MongoDB Index Removal: A Guide

In this mongodb interview process video series, we’ll tell you how should you go about removing a sql index from a collection in your MongoDB database.
To remove a database index from a MongoDB collection, use the db.collection.dropIndex(index) command.
As you do that, keep these two things in mind:

1) The default sql index on the “_id” field cannot be dropped.
2) You cannot use this function to remove all non-id sql indexes with this command starting in MongoDB 4.2. Use the function “db.collection.dropIndexes()” instead.
