Answer 1

Durable functions support this, however, they are currently supported only when using C#, F# or JavaScript.

Another options would be

1. Create HTTP request for new Azure function, however, you would have to do it in a way where your function doesn't wait for response, otherwise first function in a chain would have to wait until the very last one finishes. Using Python, that would be something like:

   try:
           requests.get("http://secondAzureFunction.com/api/",timeout=0.0000000001)
   except requests.exceptions.ReadTimeout: 
           pass
   

That seems bit hacky to me though.

2. Use Azure Storage Queues. First function passes message to a queue, which will trigger another Azure function. That seems more elegant solution. As Fabio writes here:

This keeps your functions small, fast and decoupled, while taking advantage of all the logic in place for provisioning, scaling and fault handling.
