An Introduction bulkWrite MongoDB

Did you know that the bulkWrite operation is a powerful and efficient way to perform multiple write operations in a single request in MongoDB?

In other words, it allows us to group together multiple insert, update, and delete operations, and execute them as a batch. This plays a critical role in improving performance and reducing network round-trips.

Some of the operations supported by bulkWrite() include:

• insertOne
• updateOne
• updateMany
• replaceOne
• deleteOne
• deleteMany

According to our experts, each write operation gets passed to this function as a document in an array.

For instance, here is an example of using bulkWrite in MongoDB:

const MongoClient = require('mongodb').MongoClient;
async function performBulkWrite() {
const client = new MongoClient('');
await client.connect();
const db = client.db('Bobdatabase');
const collection = db.collection('Bobcollection');
const operations = [
{ insertOne: { document: { name: 'Bob', age: 32 } } },
{ updateOne: { filter: { name: 'Barbie' }, update: { $set: { age: 26 } } } },
{ deleteOne: { filter: { name: 'Ken' } } }
];
const result = await collection.bulkWrite(operations);
console.log(result);
await client.close();
}
performBulkWrite();


Here, the bulkWrite operation is performed on the Bobcollection collection within the Bobdatabase database. The operations array contains three different write operations: an insertOne operation, an updateOne operation as well as deleteOne operation.

The result of the bulkWrite operation is an object that offers information about the execution of the bulk write, like the number of documents inserted, updated, deleted, and any error information if applicable.

According to our expert, the bulkWrite comes in handy when we need to perform multiple write operations at the same time. It allows us to send them as a single batch, reducing the overall latency and improving throughput.
