How to Perform Bulk Inserts in MongoDB Using Python?

Estimated read time 2 min read

Performing bulk inserts in MongoDB using Python can be more efficient than inserting individual documents one by one. You can use the insert_many() method provided by the pymongo package to achieve this. Here’s a step-by-step guide:

Step 1: Install the required dependencies Make sure you have Python and the pymongo package installed. You can install pymongo using pip:

pip install pymongo

Step 2: Import the necessary modules Import the required modules in your Python script:

import pymongo
from pymongo import MongoClient

Step 3: Connect to MongoDB Create a connection to your MongoDB database using the MongoClient class:

# Create a connection to MongoDB
client = MongoClient('<connection_string>')

Replace <connection_string> with the actual connection string of your MongoDB instance.

Step 4: Access a database and collection Once connected, access a specific database and collection where you want to perform the bulk insert:

# Access a database
db = client['your_database_name']

# Access a collection
collection = db['your_collection_name']

Replace 'your_database_name' with the name of your database and 'your_collection_name' with the name of your collection.

Step 5: Prepare the documents for bulk insert Create a list of documents that you want to insert in bulk. Each document should be a Python dictionary representing the data you want to insert:

# Prepare the documents for bulk insert
documents = [
    {'name': 'John Doe', 'age': 30},
    {'name': 'Jane Smith', 'age': 25},
    {'name': 'Bob Johnson', 'age': 35},
    # Add more documents as needed
]

Step 6: Perform the bulk insert Use the insert_many() method to perform the bulk insert:

# Perform the bulk insert
result = collection.insert_many(documents)

The insert_many() method returns a result object that provides information about the operation, including the inserted document IDs.

Step 7: Process the result You can process the result object to get the inserted document IDs or perform any necessary error handling:

# Process the result
inserted_ids = result.inserted_ids
print(f"Inserted document IDs: {inserted_ids}")

Step 8: Close the connection After you finish working with MongoDB, close the connection:

# Close the connection
client.close()

By following these steps, you can perform bulk inserts in MongoDB using Python. Remember to customize the code according to your specific database and collection names, and the documents you want to insert.
