Azure Functions: Is there any way to handle TimerTrigger from Azure SDK?

I am looking for a simple Scheduler to execute a task inside my Java web application deployed in Azure cloud. I am evaluating Azure functions with TimerTrigger for my requirement. Here, I am planning to define a Azure function with a callback API URL to invoke my application for executing the task inside my application.

I have some queries in this approach. Can anyone help me If you are familiar with Azure functions please?

1) Is it possible to initiate/reschedule/cancel a Azure TimerTrigger function from a Java application through API at runtime?

2) If yes, Is it possible to pass a call back URL to the timer Trigger?

3) Is there any known drawback in using Azure functions?

Thanks!

TimerTriggers don't have an api to control this (you could try to hack one in by uploading a new function.json with the schedule you want and whether or not the timer is disabled, but I don't recommend that at all).

Instead, I'd suggest using a QueueTrigger. This would allow you to pass the function any data you need in the queue item (the callback url) and you could add items to the queue with a visibility timeout in order to create your schedule. If you need to cancel pending executions, just remove the item(s) from the queue. The function is also more durable - if a queue item fails, it will automatically retry (unlike timers).

3) is way too broad of a question to have an answer.
