So far Azure Functions were related to stateless and ephemeral methods. Now with Durable Functions extensions we can build more state-full methods which allows us to do more complex execution patterns. In this session we will dive into the execution patterns that durable functions provide and explore how to use them in real life scenarios. We will cover the chaining pattern, where you can declare a series of function calls that run in sequence; and the fan-out pattern where we run multiple functions in parallel and collect results when they complete. There's even more choices and different possibilities and all that from your code without the need to learn some new DSL like in other solutions.
