Can Timer Trigger Azure function be stopped after specific operation?

Question

I have a Timer Trigger Azure function that has process to check a status from DB. Every 10 seconds, function executes and goes to check the status in DB and returns. This function should run until status is 1 or 45 seconds elapsed.

• Can I stop Azure Timer Trigger function after a specific time or based on a condition?
• Can I use System.Timers.Timer inside Azure function (non-timer trigger function)?

Please help.
