My suspicion is that this may not tell the full story. For example, availability-wise I bet there are differences between these databases. As just one example, I bet this person wasn't running with a multi-AZ setup for Upstash, since https://docs.upstash.com/overall/databasetypes says "Multi Zone Replication" is a premium feature. Whereas DDB doesn't even let you store your data in a single AZ, AFAIK (https://docs.aws.amazon.com/amazondynamodb/latest/developerg...).

(My understanding is shallow compared to real experts, but even so I know this is a deep topic and this is only one example of the type of thing you'd want to consider when figuring out whether to take this comparison at face value.)

From other comments, it appears OP is associated with upstash.
