What are bulk operations in MongoDB?
Bulk operations let you run several CRUD actions in a single request to the database, instead of sending them one at a time.
At a junior level
- Why this is needed To process large volumes of operations faster and reduce the number of round trips to the server.
- What can be done in bulk Inserts, updates, deletes, all in one batch.
- What it looks like (simplified):
js
db.users.bulkWrite([
{ insertOne: { document: { name: "Alex" } } },
{ updateOne: { filter: { name: "Alex" }, update: { $set: { age: 25 } } } },
{ deleteOne: { filter: { name: "John" } } }
])- The advantage The server processes a batch of operations faster and more efficiently than one-off requests.
Summary: bulk operations are batched CRUD actions that run in a single call, improving speed and throughput when working with a large number of documents.
