Azure durable functions and synchronous read?

Question

I'm trying to use Azure Durable Functions to implement a minimal server that accepts data via a POST and returns the same data via a GET - but I don't seem able to generate the GET response. Is it simply not possible to return the response via a simple GET response? What I do NOT want to happen is:

1. GET issued
2. GET response returns with second URL
3. Client has to use second URL to get result.

I just want:

1. GET issues
2. GET response with requested data.

Possible?

I'm not really sure whether durable functions are meant to be used as a 'server'. Durable functions are part of 'serverless' and therefore I'm not sure whether it's possible (in a clean way).

To my knowledge durable functions are used to orchestrate long lasting processes. So for example handling the orchestration of a batch job. Using durable functions it's possible to create an 'Async HTTP API', to check upon the status of the processing a batch of items ( durable function documentation ). I've wrote a blogpost about durable functions, feel free to read it ( https://www.luminis.eu/blog/azure-functions-for-your-long-lasting-logic/ ).

But as for your use case; I think you can create two separate Azure functions. One for posting your data, you can use an Azure Blob Storage output binding . Your second function can have a GET http trigger and depending on your data you can use an blob input binding. No need to use durable functions for it:)!

Not really a direct answer to your question, but hopefully a solution to your problem!
