Here's the beautiful thing about thinking serverless. "Are you really sure that it all re-ran?" Yes I am, because Dynamo streams or Kinesis streams guarantee message delivery. If my Lambda code has a bug in it, which yes sure that happens, I can as part of my exception catching, put that message into a dead letter queue and process it later or report on it. No polling, no querying, I know exactly what went wrong and when. Meanwhile, I don't have to do things like /make sure the ETL process is running/ or /clear out a bunch of logs when a disk inadvertently fills up/ or any of those other stupid last-century compute problems. It's just a far, far easier way of thinking about application development.

> Dynamo streams or Kinesis streams I can appreciate that. A lot more people than you might think, use Kafka or SQS because of various requirements (like that's all their infrastructure supports) and you end up with a massive "source" DB which is a duplication of all-time messages. Such is the reality of a larger byzantine organization. If it can't be audited by someone else, at their own pace, it's not approved.
