The async HTTP API pattern addresses the problem of coordinating the state of long-running operations with external clients.
A common way to implement this pattern is by having an HTTP endpoint trigger the long-running action. Then, redirect the client to a status endpoint that the client polls to learn when the operation is finished.
Azure Durable Functions provides built-in support for this pattern.
It contains an example about how to implement an async Http Api using Azure Durable functions and Python.
Here's a diagram that shows the dependencies between the different Azure Functions that you can find in this repository.
client-function: submits the job that needs to be executed.get-status-function: it is used to retrieve the status and the result of the submitted job.orchestrator-function: Unwraps the parameters from the submitted job and calls the activity function.query-storage-account-activity-function: Runs a custom query in an Azure Storage Table.
The Azure Storage Table connection string is stored in an Azure App Configuration.
