How to Integrate MongoDB Atlas to Snowflake? 2 Easy Methods

Every growing data team hits this point: data lives in MongoDB Atlas, insights live in Snowflake — and connecting the two feels harder than it should.

MongoDB Atlas is great at capturing complex, semi-structured data in real time. Snowflake is built to turn that data into fast, actionable insights. But moving data between them reliably and at scale? That’s where things get messy.

In this guide, we’ll explore two effective ways to move data from MongoDB Atlas to Snowflake — one powered by Hevo’s automated pipelines, and another using custom ETL scripts for full control.

Let’s get started. automated pipeline, get data flowing effortlessly—watch our 1-minute demo below to see it in action!

Method 1: Move Data from MongoDB Atlas Using CSV files

This method of moving data from MongoDB Atlas to Snowflake involves the following steps:

Step 1: Connect your Atlas database to MongoDB Compass

• Log in to your MongoDB Atlas account. Choose a cluster and click on Connect. Select the Compass version and copy the connection string provided.
• In the copied connection string, enter your username and password.

• Open MongoDB Compass on your local machine. Paste the modified connection string into the connection field in MongoDB Compass. Click Connect to establish a connection between your application and MongoDB Atlas.

Step 2: Export MongoDB Atlas data as a CSV file

• In the MongoDB Compass, navigate to the desired cluster’s database. Choose the specific collection you want to export data from.
• Click on the Export button located at the top right of the screen. A pop-up widget will appear, select the desired format, JSON or CSV, and specify the file location to save the exported document. In this case, we select the CSV file format and click the Export button to initiate the export process.

Step 3: Upload data to Snowflake

• Sign in to your Snowsight account, and navigate to the Data > Databases section.
• Select the specific Snowflake database and schema that contain the table you want to load data into.
• In the object explorer, choose the desired table and click on Load Data.
• In the Load Data into Table dialog, select Upload a file and add your CSV file from your local machine.

The manual method is particularly efficient when working with small amounts of data. This makes it a valuable option for smaller businesses or projects.

Method 2: Automating the Data Replication Process Using a No-Code Tool

Automating the data replication process using a no-code tool from MongoDB Atlas to Snowflake offers significant advantages over the manual approach.

Hevo Data is a popular no-code tool for automating data replication, offering a simple and intuitive interface for setting up data pipelines. With its pre-built connectors and templates, you can easily configure data replication workflows between MongoDB Atlas and Snowflake without complex coding. 

To migrate data from MongoDB Atlas to Snowflake using Hevo Data, follow these steps:

Step 1: Configure MongoDB Atlas as Source

Step 2: Configure Snowflake as Destination

That’s it! You have successfully connected MongoDB Atlas to Snowflake. You can now start analyzing your Atlas data using the powerful capabilities of Snowflake.

Limitations of Manually Connecting MongoDB Atlas to Snowflake:

Real-Time Sync: Manually connecting MongoDB Atlas to Snowflake lacks real-time synchronization. As a result, the data updates in MongoDB Atlas are not immediately reflected in Snowflake. Real-time synchronization would require additional mechanisms such as change data capture (CDC) or automated data integration tools with real-time replication capabilities.

Time-Consuming: Manual approach is a time-consuming and resource-intensive process. It involves uploading your Atlas data to the compass, downloading it in CSV format, and then uploading it into Snowflake using snowsight. As the size of data increases, it takes more time to download and upload the files, leading to delays in the overall data transfer.

Data Security Risks: Downloading data from one platform and uploading it to another using a CSV file poses potential security risks. Storing sensitive data in an intermediate CSV file increases the risk of unauthorized access. It’s important to ensure proper data protection measures during the manual transfer process to avoid these risks.

What Can You Achieve by Migrating Data from MongoDB Atlas to Snowflake?

There are numerous benefits of MongoDB Atlas to Snowflake data migration. Here are some of them:

1. Analyzing Individual Interaction Data

By integrating MongoDB Atlas with Snowflake, you can analyze this data at scale, leveraging Snowflake’s analytics capabilities. This lets you gain insights into user behavior, track events, and optimize user experience.

2. Customer Journey Analysis

Centralizing the data would help you get an overview of your customer journey. You can combine different business operations data like sales, marketing, and user engagement to understand the behavioral patterns of your customers.

3. Data Sharing and Collaboration

Snowflake allows you to securely share your data with internal teams, partners, or customers. By migrating MongoDB Atlas data to Snowflake, you can easily share selected datasets with relevant stakeholders, enabling collaborative data analysis or third-party integrations.
