Patterns for composing and coordinating multiple units of work within a Workflow.

- [Child Workflows](/design-patterns/child-workflows): Decomposes complex Workflows into smaller, reusable units. Each child has an independent Workflow ID, history, and lifecycle.
- [Parallel Execution](/design-patterns/parallel-execution): Executes multiple Activities concurrently for maximum throughput with error handling and controlled parallelism.
- [Pick First (Race)](/design-patterns/pick-first): Starts multiple Activities in parallel and uses the first result, cancelling the rest.
