Parallelization
Independent sub-tasks run concurrently instead of sequentially — through async recipe calls or concurrent genie runs, not "parallel recipe branches."
Why This Pattern
The reasoning trigger is purely: are these units of work independent of each other's results? If yes, running them sequentially is pure waste — the only remaining question is which layer to parallelize at. Get the independence check wrong, and you get race conditions and inconsistent state, which is exactly why this is never "branches": IF/ELSE branches are mutually exclusive by design, so there's nothing to parallelize there in the first place.
When to Use It
- Multiple recipe calls or genie invocations are independent of each other's results.
- You're processing many similar items (e.g., 50–100 expense lines) and looping through them one at a time is too slow.
When NOT to Use It
- Later steps depend on an earlier step's output — that's Guided Skill Chaining, not Parallelization.
- You're tempted to reach for recipe IF/ELSE branches for concurrency — they're mutually exclusive by design and won't give you it.
How It Works in Workato
Recipe level: Call recipe (asynchronous) fires off independent recipe calls without waiting; a Wait for async calls action blocks until they all finish. Genie level: a recipe orchestrator invokes Assign Task to Genie inside a Repeat for each loop, so multiple genie instances process line items concurrently.
