In this recipe, we will create, read, update, and delete items. We will learn to query and scan data with eventual consistency, as well as strong consistency. We will discuss the AWS CLI commands to work with data in this recipe, followed by recipes that use Java code from Lambda function using AWS Java SDK for DynamoDB.

We discuss only the essential DynamoDB concepts and commands, to get you started working with DynamoDB to build serverless applications with DynamoDB as the data store. You may explore further in the AWS documentation, a dedicated book, or a course on DynamoDB to master DynamoDB concepts.
