Fork me on GitHub

I'm trying to decide between using RDS Aurora vs DynamoDB. I have read a few blog posts + watched a few youtube videos. What would really help me would be seeing a list of sample apps, and how they would be implemented in Aurora / DynamoDB (or maybe only one of the two). Is there a list of this somewhere? (The impl does not have to be CLJS -- plain JS is fine -- I just need to see when Aurora is used vs when DynamoDB is used.)
