9:50 is there any scenario when writing cloudformation script is actually better than deploy code using serverless framework since SLS is way easier and time efficient than cfn.

Hi Alex, a quick question for you. I've been trying to wrap my head around DynamoDB data modelling desing for a few days now. I have a scenario where I have 3 related entites such as video stream, product group and product item. We have a 1 to 1 relationship between a stream and a product group and a 1 to many realationship between a product group and a product item. As you can tell it's still hard for me to think out of the relational box and this is the main reason why I want to use a NoSQL db for my project. My question is can these be achieved with the single-table design and if so what would be the best way to aproach it? All of your examples I found on-line take into consideration only a one-to-many scenario. Thank you, and all the best. David
