Are you using DynamoDB Streams at all? I've been toying the idea of using DynamoDB as an event store and having other services listen to a table's stream, allowing them to update caches/views (the read-side of CQRS), report analytics, perform asynchronous tasks, etc.

You could quite nicely use AWS Lambda for the materialized views, I think.

No, haven't tried them yet. Does look interesting for it, though.
