What Are The Delete Methods Available In MongoDB?

The following techniques are available in MongoDB for removing documents from a collection:

db.collection.deleteOne(): Even though numerous documents may meet the specified filter, only one document that matches the filter should be deleted.

db.collection.deleteMany(): Eliminate every document that fits a given filter.

db.collection.remove(): Eliminate a specific document or every document that fits the given filter.

Starting in MongoDB 6.1:

• MongoDB may batch delete several documents at once in order to increase efficiency.
• There is a new BATCHED_DELETE stage for batch document deletions in the explain command results.

Additional Methods

Documents from a collection can also be removed using the following techniques:

• db.collection.findOneAndDelete(): The sort option is provided by findOneAndDelete(). The first document sorted in the designated order may be deleted with this option.
• db.collection.findAndModify().
• db.collection.findAndModify() offers a sorting option. The first document sorted in the designated order may be deleted with this option.
• db.collection.bulkWrite().
