In Chapter 1, Developing Cloud Applications Using Function Triggers and Bindings, you learned how to create a queue message for each request coming from the HTTP request. Now, let's assume that each user is registering their devices using client applications (such as desktop apps, mobile apps, or any client websites) that can send multiple records in a single request. In these cases, the backend application should be smart enough to handle the load coming to it; there should be a mechanism to create multiple queue messages at once and asynchronously. You will learn how to create multiple queue messages using the IAsyncCollector interface.
Here is a diagram that depicts the data flow from different client applications to the backend web API:
In this recipe, we will simulate the requests using Postman,...
