Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. It's a key-value and document database that delivers single-digit millisecond performance at any scale.

Tables and Items

DynamoDB stores data in tables. Each table contains items, and each item is a collection of attributes. DynamoDB uses primary keys to uniquely identify each item in a table.

Capacity Modes

DynamoDB supports two capacity modes: On-Demand and Provisioned. On-Demand mode automatically scales to accommodate your workload, while Provisioned mode requires you to specify read and write capacity units.

Global Tables & Streams

DynamoDB Global Tables provide multi-region, multi-master replication. DynamoDB Streams captures item-level changes and can trigger Lambda functions or replicate data.

DynamoDB Glossary

DynamoDB: A fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. It's a key-value and document database.
Table: A collection of items in DynamoDB. Each table must have a primary key that uniquely identifies each item.
Item: A collection of attributes in a DynamoDB table. Each item is uniquely identified by its primary key.
Primary Key: Uniquely identifies each item in a table. Can be a simple primary key (partition key) or composite primary key (partition key + sort key).
On-Demand Mode: A capacity mode that automatically scales to accommodate your workload. You pay only for what you use, with no capacity planning required.
