I've spent the last year using AWS DynamoDB at work. When we initially searched for a Scala client for DynamoDB, we had the following criteria:

• Good for Scala beginners
• Up to date
• Well documented

Sadly, none of the Scala libraries available at that time matched all three criteria. The most up-to-date libraries were not suitable for a team starting out with Scala and DynamoDB. The most beginner-friendly libraries were out-of-date, and most only had superficial documentation.
