Using Durable Functions for Fan Out Fan In Pattern | Functions | AZ-204 | LSC

Hi Everyone,

In serverless computing, parallel processing is essential to handle large workloads efficiently. The fan-out/fan-in pattern represents a popular approach for parallel processing, where it splits a single operation into multiple sub-operations, executes them in parallel, and merges their results to produce the final output. Durable Functions in Azure provides a powerful way to implement the fan-out/fan-in pattern.

In this video, we will show you how to use Durable Functions to implement the fan-out/fan-in pattern using an example. We will walk you through the code for an orchestrator function that calls two activity functions in parallel and waits for their results to be returned before continuing.
