When it comes to choosing the right database for your business, it can often be a daunting task.
There are a plethora of choices available. Two of the most popular are Cassandra and DynamoDB.
Both have their own unique features and benefits, and understanding the differences between the two is essential for finding the perfect fit for your company.
Cassandra is an open-source, distributed NoSQL database, while DynamoDB is a proprietary NoSQL database from Amazon Web Services.
Both can provide data storage and retrieval capabilities, but the differences between the two should be carefully considered.
This article will explore the key differences between Cassandra and DynamoDB, helping you make the best decision for your business.

Overview of Cassandra and DynamoDB
Cassandra
- Cassandra is a distributed NoSQL database that can be used to handle large amounts of unstructured data.
- It uses a schema-less data model, meaning that data doesn’t need to be structured or formatted a certain way.
- This makes it an ideal database for storing data that does not fit into predefined tables and columns.
- Cassandra is built on the concept of data distribution, so the data is split up and put across multiple nodes.
- This makes it highly scalable, allowing it to expand as needed.
- This is useful for businesses that are dealing with increasing amounts of data and require a database that can expand as they grow without experiencing downtime.
DynamoDB
- DynamoDB is another distributed NoSQL database that can be used as a data store.
- It was created by Amazon Web Services, and is often used by businesses that need to store and access large amounts of unstructured data.
- DynamoDB uses a centralized data model, meaning that data is structured into tables and columns.
- It is essentially a database-as-a-service with built-in security features, scalability options, and high availability.
- It is a great option for businesses that want the simplicity of managed database hosting.
Here is a comparison of Cassandra and DynamoDB in table form:
| Feature | Cassandra | DynamoDB |
|---|---|---|
| Data model | Wide-column | Key-value |
| Indexing | Secondary indexes (not as efficient as primary key) | Up to 20 global secondary indexes and 5 local secondary indexes |
| Consistency | Tunable consistency | Eventual consistency |
| Pricing | Fixed-price (based on number of nodes and storage) | Pay-per-request (based on number of read and write requests) |
| Use cases | Storing large amounts of data with flexible schemas | Simple key-value storage with the ability to scale horizontally |
