MongoDB is a popular open-source NoSQL database that stores data in a flexible, document-based format. It is designed to handle large volumes of unstructured data and is highly scalable, making it a popular choice for modern web applications. MongoDB uses a JSON-like format to store data, which allows for easy integration with web applications and APIs. It also supports dynamic queries, indexing, and aggregation, making it a powerful tool for data analysis. MongoDB is widely used in industries such as finance, healthcare, and e-commerce, and is known for its ease of use and flexibility.
A fully managed data warehouse service in the Amazon Web Services (AWS) cloud, Amazon Redshift is designed for storage and analysis of large-scale datasets. Redshift allows businesses to scale from a few hundred gigabytes to more than a petabyte (a million gigabytes), and utilizes ML techniques to analyze queries, offering businesses new insights from their data. Users can query and combine exabytes of data using standard SQL, and easily save their query results to their S3 data lake.

As diversity and use cases of data are evolving rapidly, switching between different database management systems is becoming normal for organizations.
If you are here, you might need to shift from MongoDB to Redshift. MongoDB is a non-relational database widely used by organizations to handle various data formats, high-speed data ingestion, and powerful query language. On the other hand, Redshift is a relational storage system used for its analytical capabilities, query performance, and storage capacity. Since both databases have different use cases, migration becomes an obvious choice for varying business requirements.
This article will discuss migrating MongoDB to Redshift ETL using two easy methods.
MongoDB Overview

Created in 2009, MongoDB is a modern NoSQL database. Being non-relational, it follows a document-oriented approach and stores data in documents that consist of key-value pairs and follow a BSON (Binary JavaScript Notation) structure. Unlike relational databases, MongoDB has no structural limitations. Therefore, it can process structured, semi-structured, and unstructured data. Additionally, its modern architecture and cutting-edge features like load balancing, query performance, and indexing make it stand out from other NoSQL databases.
Some of the key features of MongoDB include:
- Schema-less Database: As a NoSQL database, MongoDB is schema-less, which means you can store different types of documents in one collection. In a MongoDB database, a single collection can hold multiple documents, and each document may consist of different numbers of fields and contents.
- Indexing: Indexes are unique data structures that store some information related to documents, making it easy for MongoDB to find the right data file. If the data is not indexed properly, the database searches each document with specified queries, which is time-consuming.
- Rich Query Language: MongoDB has a rich query language for data querying and manipulation. You can use it to run searches for filtering data, sorting results, or even perform geospatial queries to locate data based on its coordinates.
Redshift Overview

Amazon Redshift is a cloud data warehousing solution provided by Amazon Web Services (AWS). It can handle and process huge amounts of structured and unstructured data in the range of exabytes (10*18 bytes). Some of the well-known organizations that use Redshift in their tech stack include Amazon, Lyft, Figma, and Coursera.
Key features of Redshift include:
- Petabyte Scale Data Warehouse: The distributed architecture of storage in Redshift supports workloads of up to 8 PB of compressed data. With this robust storage capacity, you can handle almost any number or type of nodes in your data warehouse.
- Federated Query: The federated query feature of Redshift allows you to query live data across one or more databases without the need for data migration. This includes querying from Amazon's Relational Database Services (RDS), including Aurora MySQL Aurora PostgreSQL, and getting results as temporary tables.
- Serverless: Redshift offers a serverless architecture for data management. With this feature, you can manage any size of analytical workload without the need to manage a data warehouse's resources. Therefore, you can focus on the analytics rather than managing infrastructure.
Why Migrate From MongoDB to Redshift?
MongoDB and Redshift complement each other. While MongoDB is known for handling evolving and unstructured data, Redshift outshines it in analytical processing. Below are some of the key reasons for migrating MongoDB to Redshift:
Data Warehousing
MongoDB: MongoDB is not a data warehouse. It offers a flexible NoSQL database that can handle diverse data types, including structured, semi-structured, and unstructured data.
Redshift: Redshift is a data warehouse. It lets organizations store data from one or more sources in a centralized repository. So that organizations can connect multiple databases of downstream applications into one data warehouse. This allows organizations to do cross-functional analysis and unify their data by creating a single source of truth.
Business Intelligence & Reporting
MongoDB: MongoDB is ideal for handling transactional workloads and real-time applications. However, the analytical capabilities of MongoDB are not as robust as a dedicated data warehousing solution.
Redshift: Redshift streamlines the integration with well-known BI tools like Tableau and Power BI to extract meaningful insights from the organization's data. Organizations can use these BI capabilities to make data-driven decisions.
Scalability
MongoDB: MongoDB provides horizontal scalability, which allows organizations to scale their database easily by adding more servers to a MongoDB cluster.
Redshift: Redshift offers a Massively Parallel Processing (MPP) architecture to handle large datasets. Organizations can choose to add more computing resources to the Redshift cluster to scale up their analytics processing requirements.

Method 2: Manually Connecting MongoDB to Redshift
In this method, we will manually migrate data from MongoDB to Redshift. It involves exporting data from MongoDB in JSON format, uploading it to the S3 bucket, and moving it to Redshift. Here's a detailed guide:
Prerequisites
- Amazon S3.
- A SQL Client.
- Windows Powershell.
Step 1: Export Data From MongoDB
- Access your MongoDB database using the command prompt.
- Type the following command on the terminal to export data from your MongoDB collection in JSON format:
Replace db-name with the name of the database, collection-name with the collection you want to export, and output-file.json with your desired file name.
Step 2: Upload JSON file to S3 bucket
- Sign up or log in to the AWS Management Console and navigate to the Amazon S3 service.
- Create a new bucket or use an existing one on S3.
- Upload the JSON file you exported from MongoDB on the S3 bucket.
Step 3: Create a Table in Redshift
- Access your Redshift cluster using a SQL client.
- Now, create a table schema in Redshift that matches the structure of MongoDB data in a JSON file. Type the following code in the SQL client:
Replace your_table with the desired table name and define columns according to the JSON file structure.
Step 4: Copy Data From S3 to Redshift
- On the SQL client, type the following code to copy data from the S3 bucket to the Redshift table:
In the above code, replace your_table with your table name, s3_path with a path to your JSON file in S3, your_access_key_id, and your_secret_access_key with AWS credentials.
Done. By following these steps carefully, you'll successfully export data from MongoDB, upload it on S3, and load it in Redshift.
Conclusion
Migration from MongoDB to Redshift can benefit organizations looking to enhance their analytical workloads and query performance. In this article, you have seen two popular methods for migrating data from MongoDB to Redshift. One method uses a SaaS tool - Airbyte, to streamline the process of migrating data. The other uses JSON files to migrate data manually.
Both of these methods are widely used and have their use cases. However, using Airbyte, you can perform data migration within just a few clicks, and it automatically syncs the data if changes are made. However, in the manual method, you don't need a tool for migrating data, and the process is time-consuming and error-prone.
