I think you need to revise your assumptions. Even optimized DynamoDB setups shows average response times in the 15ms range and P99s at the 20ms range.
One of the mistakes you seem to be making is assuming that to do a query on a globally distributed database with multiple partitions, you'd only need to hit one single box and no data exchange would take place. That bears no resemblance with reality.
