This approach is particularly useful with the TaskFlow API, where a task's return value is automatically pushed to XCom. By explicitly passing these references as arguments to downstream tasks, you create an intuitive, functional declaration of your pipeline.
Overview: Have producers LPUSH (or RPUSH) payloads to a Redis list and consumers use RPOP (or LPOP) to consume items, ensuring each item is removed once and processed by at most one consumer. airflow xcom exclusive

To run high-scale, zero-downtime data platforms, you should apply these exclusive XCom design patterns. Pattern 1: Dynamic Task Mapping with XComs This approach is particularly useful with the TaskFlow
