 A big thank you to [Alex DeBrie](https://www.alexdebrie.com/about/) and his excellent [DynamoDB Book](https://www.dynamodbbook.com/). Highly recommended. And thanks also to [Jeremy Daly](https://www.jeremydaly.com/about/) for his [Off by None Blog](https://offbynone.io/) blog, posts and his [DynamoDB Toolbox](https://github.com/jeremydaly/dynamodb-toolbox) which pointed out a better way for us to do a number of things.
