A simple stitch app to run as a cron service on MongoDB Stitch, using MongoDB TTL.
This repository contains a stitch app configured as a database trigger for a DELETE event.
The DELETE event occurs when a document within a collection containing a TTL index is deleted. The app then inserts a new document into the collection with the current date, thus causing a rough timed loop.
