S3 also doesn't provide a linearizable consistency model or even a vague approximation of one. You can't rely on the events you try to schedule happening in the order you try to schedule them in, or even happening at all.

This seems overcomplicated compared to using a regular timed event to trigger a lambda and having it decide what to execute conditionally.

I wasn't really too worried about picking apart the approach. If order mattered, you'd be looking at other approaches anyway.

Mainly just calling out a gotcha where you might quietly miss out on scheduled events with no warning.

For example:

1. Object written to successfully to bucket.

2. `s3:ObjectCreated:Put` is _never_ delivered.

The possibility of duplicate events are warned about a lot in the AWS ecosystem, and this sets up an expectation of "at-least-once" delivery.
