Seems like any key value store would be better for this. Redis, DynamoDB, etc.. could get a lot higher throughput on messages.

It's not about the throughput though, but about consistency. You can't do the same thing on Redis if it's not your main storage. You need to have transactions on level of the database engine your application uses.
