XComs are designed for , such as configuration strings, timestamps, flags, or small IDs.
Apache Airflow is the industry standard for workflow orchestration, allowing data engineers to build robust, DAG-driven data pipelines. By design, Airflow tasks are isolated units of work, often running on entirely different machines or containers. While this separation is essential for scalability, it introduces a challenge: Enter Airflow XComs (cross-communication).
