To get the most out of this book

We recommend reading AWS DynamoDB Developer Guide alongside this book to get a comprehensive view of the specifics. Given that technology evolves, some limits or feature supports may have been updated since the book was published. Note also that console screenshots may differ from the latest version, but features and functionalities remain consistent. For the latest details, always refer to the AWS documentation. This book complements the documentation by offering insights and best practices drawn from more than a decade of combined DynamoDB and NoSQL experience.

While trying out the code examples can enrich your understanding, it is not mandatory. Note that using AWS features may incur costs, typically between $2 and $5 if resources are utilized and deleted within the same hour, with costs potentially increasing if resources remain active longer.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
