Introduction

Amazon DynamoDB is a fully managed and cloud-hosted NoSQL database. NoSQL databases allow us to have a schema-less design for the tables. We only need to define the key, and the rest of the attributes can be defined at the time of record insertion itself.

DynamoDB provides a fast and predictable performance with the ability to scale seamlessly. It allows you to store and retrieve any amount of data, serving any level of network traffic without having any operational burden. DynamoDB gives numerous other advantages, such as a consistent and predictable performance, flexible data modelling, and durability. This chapter is all about taking your first steps with DynamoDB, getting your workspace ready, and seeing how to perform DynamoDB operations using the DynamoDB console.
