DynamoDB cannot store empty strings
I used DynamoDB for an inherited project around the time I had gotten really good with MongoDB. I don't have any idea why anyone would ever use DynamoDB. It's like Mongo, without any of the good parts, that you can't run locally or any non-Amazon server. I don't see the benefit.Edit: Specifically, I was using some pretty advanced aggregation stuff. At the time I used it, DynamoDB had zero aggregation whatsoever.
