DynamoDB vs MongoDB: Choosing the best NoSQL

Nov 27, 2020


In the world of NoSQL databases, DynamoDB and MongoDB have gained significant popularity among businesses looking for scalable and flexible database solutions.

Understanding DynamoDB

DynamoDB is a fully managed, serverless NoSQL database service provided by Amazon Web Services (AWS). It offers seamless scalability, high performance, and built-in security.

  • Scalability: DynamoDB is designed to scale automatically to handle millions of requests per second, making it an excellent choice for applications with unpredictable workloads.
  • Performance: With DynamoDB, you can achieve single-digit millisecond response times at any scale, ensuring low-latency access to your data.
  • Security: Amazon provides robust security features, including encryption at rest and in transit, data backups, and fine-grained access control.

Exploring MongoDB

MongoDB is a widely-used open-source document database, known for its flexibility and developer-friendly features. It offers powerful querying capabilities and schema-less design.

  • Flexibility: MongoDB allows you to store and manipulate data of any structure, making it suitable for evolving or constantly changing data requirements.
  • Querying: With MongoDB's expressive query language, you can easily retrieve and manipulate complex data structures with support for rich queries, aggregation pipelines, and indexes.
  • Community Support: MongoDB has a large and active community, providing extensive resources, documentation, and community-driven tools and libraries.

Differences Between DynamoDB and MongoDB

1. Data Model

DynamoDB is a key-value store, while MongoDB is a document database. This fundamental difference determines how data is structured and accessed in each database.

2. Scalability and Performance

DynamoDB offers seamless scalability and automatic load balancing, ensuring high performance even under heavy workloads. MongoDB provides horizontal scalability through sharding but requires more manual configuration.

3. Schema Design

DynamoDB requires specifying a schema upfront, which can provide better performance for simple and predictable use cases. MongoDB's flexible schema allows for easy adaption to changing requirements but may result in a higher overhead for complex queries.

4. Cost

DynamoDB pricing is based on provisioned throughput and storage, while MongoDB can be more cost-effective for applications with predictable workloads or smaller datasets.

Choosing the Best NoSQL Database

Ultimately, the choice between DynamoDB and MongoDB depends on your specific use case and requirements. Consider the following factors:

  • Workload: If you have a highly dynamic workload with unpredictable traffic patterns, DynamoDB's auto-scaling capabilities may be advantageous.
  • Data Structure: If your data has a complex and evolving structure, MongoDB's flexible schema design may be more suitable.
  • Developer Experience: Evaluate the developer experience and available libraries, considering your team's familiarity with either DynamoDB or MongoDB.
  • Cost Considerations: Analyze your expected usage patterns and data volumes to determine the most cost-effective option.


Both DynamoDB and MongoDB are robust NoSQL databases, each with their own strengths and considerations. To choose the best NoSQL database for your business, evaluate your workload, data requirements, scalability needs, and developer preferences to make an informed decision.
