Creating dynamically scheduled functions

Question

I have a list of 10 time stamps which keeps on updating dynamically. In total there are 3 such lists for 3 users. I want to build a utility to trigger a function at the next upcoming time stamp. (preferably everything over server-less compute)

I am stuck in finding out how to achieve this over aws or firebase

Answer 1

On Firebase/Google Cloud Functions the two most common options are either to store the schedule in a database and then periodically trigger a Cloud Function and run the tasks that are due, or to use Cloud Tasks to dynamically schedule a callback to a separate Cloud Function for each task.

I recommend also reading:

• Doug's blog post on How to schedule a Cloud Function to run in the future with Cloud Tasks (to build a Firestore document TTL)
• Fireship.io's tutorial on Dynamic Scheduled Background Jobs in Firebase
• How can scheduled Firebase Cloud Messaging notifications be made outside of the Firebase Console?
• Previous questions on dynamically scheduling functions, as this has been covered quite well before.
