Why is DynamoDB so popular?
MongoDB and DynamoDB are two popular NoSQL databases. However, DynamoDB has been gaining popularity over MongoDB due to its serverless and easy-to-use nature as well as better security.
Why DynamoDB is used in AWS?
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. For more information, see DynamoDB Encryption at Rest. With DynamoDB, you can create database tables that can store and retrieve any amount of data and serve any level of request traffic.
What is DynamoDB best for?
Conclusion. As a non-relational database, DynamoDB is a reliable system that helps small, medium and large enterprises scale their applications. It comes with options to backup, restore and secure data, and is great for both mobile and web apps.
How can DynamoDB improve performance?
To Summarize: You can increase your DynamoDB throughput by several times, by parallelizing reads/writes over multiple partitions. Use DynamoDB as an attribute store rather than as a document store. This will not only reduce the read/write costs but also improve the performance of your operations considerably.
Is DynamoDB good for analytics?
You can reap huge analytical value from billions of items and millions of requests per second in your Amazon DynamoDB service. However, you need to export your data in order to get that analytical value. Copying the data from a DynamoDB table to an analytics platform allows you to extract rich insights.
Why is DynamoDB so fast?
Developers can store and retrieve any amount of data and DynamoDB will spread the data across more servers as the amount of data stored in your table grows. Fast. Amazon DynamoDB provides high throughput at very low latency.
Why is DynamoDB serverless?
Benefits of using DynamoDB as a serverless developer DynamoDB provides both provisioned and on-demand capacity modes so that you can optimize costs by specifying capacity per table, or paying for only the resources you consume. You are not provisioning, patching, or maintaining any servers.

What is the best practices for designing and using partition key effectively in DynamoDB?
Six DynamoDB Key Design Best Practices
- Ensure Data Uniform Distribution Across Partitions.
- Ensure Uniform Distribution of Read and Write Patterns.
- Segregate Hot and Cold Data into Different Tables.
- Query Operations Over Scan Operations and Filters.
- Local Secondary Index vs Global Secondary Index.
