You haven't missed much. The overall developer experience is still... poor.

Dynamo has its use cases. Imagine a database with 100K+ of devices sending different metrics out every minute or so. You need to retrieve metrics by device ID:metric and date/time range. I migrated a similar DB from Cassandra to Dynamo, and it worked really well (for that use case!)

In the years since, I've worked at other companies and seen Dynamo used where it was a really poor fit: tons of filtering/scanning, relatively tiny datasets that require many secondary indexes. I even know of one app that starts up and loads an entire DDB table into memory! If you're not absolutely sure Dynamo is a good fit, it isn't. Use a relational database.
