AWS Scheduling Mechanism?

Question

I want to delay an email being sent for X days. This could be days, weeks, or months.

Is there anything out there other than Step Functions?

Some concerns I had with Step Functions, which could be debunked:

• The longest wait cannot exceed a year
• If the stack is deleted during long running waits. Does that in turn delete the wait task?

Answer 1

Check this solution out. It should be what you need. It is a combination of Step Function and the DB solutions mentioned above which addresses the issues being raised (max wait time and inefficient scanning).

Answer 2

You can define an event rule in either Cloudwatch or EventBridge that triggers on a schedule (fixed or based on cron expression). The event target can be either SNS Topic or a Lambda function to send the email.
