Hooks integrate with connections with encrypted credentials and API tokens stored as metadata. They can create instances in Airflow environments to connect quickly with APIs and databases using hooks (interfaces), without writing low-level code. Each task is scheduled or triggered after an upstream task is completed and implemented as a Python script-defined in DAG files that contain metadata about its execution.Īirflow solutions allow users the ability to run thousands of tasks and have many plugins and built-in operators available that integrate jobs in external systems or are customized for specific use cases.Īpache Airflow solutions are used for batch data pipelines. The DAG is the center that connects all the Airflow operators and lets you express dependencies between different stages in the pipeline. Tasks are represented as nodes and have upstream and downstream dependencies that are declared to create the DAG structure. The DAG defines the tasks and executions, running order, and frequency. A Directed Acrylic Graph (DAG) is a graph coded in Python that represent the overall pipeline with a clear execution path-and without loops or circular dependencies. Data pipelines involve the process of executing tasks in a specific order.Īpache Airflow is designed to express ETL pipelines as code and represent tasks as graphs that run with defined relationships and dependencies. What is Apache Airflow?Īpache Airflow is an open-source data pipeline orchestration platform (workflow scheduler).Īpache Airflow orchestrates components for processing data in data pipelines across distributed systems. Integrate data from internal and external sources connecting to third-party APIs and data stores in a modular architecture.
