Dynamic Task Mapping With Runtime Expansion

Industry-standard workflow orchestration.

Unique: Runtime expansion of tasks based on data, avoiding DAG code generation or complex conditional logic. Mapped task outputs automatically aggregated via XCom, allowing downstream tasks to consume results without explicit looping. Scheduler evaluates expansion at runtime, enabling truly dynamic parallelism based on query results or external data.

vs others: More elegant than DAG-generation approaches (Prefect's dynamic tasks, Dagster's dynamic outputs) because expansion happens in scheduler, not in DAG definition code. Simpler than manual fan-out/fan-in patterns but with less control over aggregation strategy.
