Why did you go with a non-relational database?

Interesting question. No-SQL doesn't mean non-relational. DynamoDB is a relational database. It's up to you on how you design the table to accommodate your relations.

This is a great presentation about this: https://youtu.be/6yqfmXiZTlM?t=1447

DynamoDB is a key-value store. Key-value stores are not relational databases [1]

The link you posted is a really good resource for someone who wants to start using DynamoDB though.

You're right. DynamoDB is not a relational database. But data in DynamoDB can be relational just as in a regular relational database: https://docs.aws.amazon.com/amazondynamodb/latest/developerg...

That's really stretching the definition of a 'relational database'.

You can create relationships on flat text files. It doesn't mean that you have a relational database now.

Many have fallen for that marketing video stunt and later regret it.
