Getting started with DynamoDB in awstin

This tutorial follows the “Getting Started” guide for DynamoDB and Python in the boto3 docs. That reference can be found here.

Equivalent tutorials are presented for each section, except for the first and last sections on creating and deleting tables. These functions of boto3 are out-of-scope for awstin, leaving infrastructure management to dedicated IaC frameworks or to boto3.

In each case, the structure of the examples are kept as comparable as possible to the examples in the boto3 docs.

Note that when using DynamoDB in awstin, either the AWS_REGION (in production) or the TEST_DYNAMODB_ENDPOINT (in integration tests) environment variable should be set. This will be used to connect either to the real AWS DynamoDB service or to a testing instance of DynamoDB.
