🎓 Optimize Speed-Critical Workflows Using Parallel Processing (Fan-Out/Fan-In)

How it works This template is a hands-on tutorial for one of the most advanced and powerful patterns in n8n: asynchronous parallel processing, also known as the Fan-Out/Fan-In model. When should you use this? Use this pattern when speed is your top priority and you have multiple independent, long-running tasks. Instead of running them one after another (which is slow), this workflow runs them all at the same time and waits for them all to finish. We use a Construction Project analogy to explain the architecture: The Main Workflow (Top): This is the Project Manager. It defines the project, assigns all the tasks to specialist teams, and then pauses, waiting for a final report. The Sub-Workflow

Help me set up the n8n workflow "🎓 Optimize Speed-Critical Workflows Using Parallel Processing (Fan-Out/Fan-In)" (https://n8n.io/workflows/6247). It uses: HTTP Request, Code, AI Agent, Google Gemini Chat Model. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
