Redis is already super useful, but this would be an absolutely killer feature. Server assisted client side invalidation! Something people have always wanted but has never been built.

It's definitely at least network-based, b/c you have to spin up instances of it in your VPC.
However, they also require custom clients, which is a little odd afaiu (b/c in theory DAX is API-compatible with DynamoDB, so why would regular dynamodb sdk clients not work?) so maybe the custom clients also add some in-process-based caching?
