Learn how to perform many operations at once in MongoDB using bulkWrite()! This is the most efficient way to insert, update, or delete thousands of documents in a single command.

We'll also cover the essential upsert option, which lets you update a document if it exists, or insert it if it doesn't.

What you will learn:

db.collection.bulkWrite(): The main command for performing bulk operations.

How to perform mixed operations: We'll show you how to combine insertOne, updateOne, updateMany, and deleteOne all in one bulkWrite call.

The upsert: true Option: How to use upsert within an updateOne or updateMany operation to create a new document if no match is found.

Example bulkWrite with upsert: db.products.bulkWrite([ { insertOne: { document: { name: "New Product" } } }, { updateOne: { filter: { sku: "12345" }, update: { $set: { price: 99.99 } }, upsert: true } }, { deleteOne: { filter: { status: "old" } } } ])
