About Amazon DynamoDB
Amazon DynamoDB is a serverless key-value NoSQL database from AWS. It is built to give consistent, single-digit millisecond response times as traffic grows.
What it does
DynamoDB handles servers, scaling and maintenance, so developers mostly work with tables, items and keys. It can bill per request or use provisioned capacity, and warm throughput helps prevent delays from cold starts. Global tables replicate data across AWS Regions for applications that need multi-Region access. Native vector search supports AI apps that need semantic retrieval.
Key features
- Serverless, with no servers to manage
- Single-digit millisecond response times
- Global tables across AWS Regions
- Native vector search
- Continuous backups
Who it's for
Teams building on AWS with variable traffic, and developers who want a database without managing servers. Teams building AI agents that need fast lookups may also consider it.
Pricing and good to know
DynamoDB has pay per request billing, and AWS offers a free tier to try it. Costs grow with reads, writes and storage, so model your usage before launch. Modelling data for key-value access is different from relational SQL design, so plan your key structure early.
