TaskFlow-decorated custom Python functions are packaged as a Task.Sensors are a subtype of Operators that are solely concerned with waiting for an external event to occur.Operators are preconfigured task templates that you can quickly string together to form a majority of your DAGs.To get further information on Apache Airflow, check out the official website here. To orchestrate an arbitrary number of workers, Airflow generates a message queue. You are free to create as many dependent workflows as you like. Scalable: Airflow has been built to scale indefinitely.In Airflow, parameterizing your scripts is a simple process. User Interface: Airflow creates pipelines using Jinja templates, which results in pipelines that are lean and explicit.You can also customize the libraries to fit the level of abstraction that best suits your needs. Versatile: Since Airflow is an Open-source platform, users can create their own unique Operators, Executors, and Hooks.There are several operators, hooks, and connectors that may be used to generate DAG and connect them to form processes. Dynamic Integration: Airflow generates dynamic pipelines using Python as the backend programming language.A Dependency Tree is created by connecting nodes with connectors. The workflow is built with Apache Airflow’s DAG (Directed Acyclic Graph), which has nodes and connectors. Airflow is used to organize complicated computational operations, establish Data Processing Pipelines, and perform ETL processes in organizations. Table of ContentsĪpache Airflow is an Open-Source process automation and scheduling tool for authoring, scheduling, and monitoring workflows programmatically. In this article, you will get to know everything about Airflow Tasks and understand the important terms and mechanisms related to the Airflow Tasks. Tasks are organized into DAGs, and upstream and downstream dependencies are established between them to define the order in which they should be executed. In Airflow, a Task is the most basic unit of execution.
