-## Scheduling Tasks
-This example processes failed payment events from a payment provider.
-The service reminds the customer for 3 days to update their payment details, and otherwise escalates to support.

-To schedule the reminders, the handler uses Restate's durable timers and delayed calls.
-The handler calls itself three times in a row after a delay of one day, and then stops the loop and calls another handler.
