WHAT IS AIRFLOW SOFTWARE

Open Matt Davis: A Practical Introduction to Airflow | PyData SF 2016 on YouTube. With dependencies specified between tasks, Airflow knows which ones it can run in parallel and which ones must run after others. A single pipeline might contain bash, Python, and SQL operations.

WHAT IS AIRFLOW SOFTWARE

In an introduction to the technology, Matt Davis, a senior software engineer at Clover Health, explains that it enables multisystem workflows to be executed in parallel across any number of workers. SensorsВ that keep running until a certain criterion is met, such as a specific file landing in HDFS, a partition appearing in Hive, or a specific time of the day.TransferВ operators that move data from one system to another.Those that perform an action, or tell another system to perform an action.The Airflow scheduler executes tasks on an array of workers while following the specified dependencies.ДAG operators define individual tasks to be performed, though custom operators can be created. Though based in Python, it can execute programs in other languages as well. With Airflow, users can create workflows as directed acyclic graphs (DAGs) to automate scripts to perform tasks. ItвЂ™s designed to be dynamic, extensible, lean and explicit, and scalable for processing pipelines of hundreds of petabytes. It entered the ASF incubator in March 2016. Maxime Beauchemin created Airflow in 2014 at Airbnb. It touts command-line utilities for performing complex surgeries on DAGs and the user interface for providing visibility into pipelines running in production, making it easy to monitor progress and troubleshoot issues. Airflow providesВ smart scheduling, database and dependency management, error handling and logging. When workflows are defined as code, they become more maintainable, versionable, testable, and collaborative, according to the projectвЂ™s GitHub page. вЂњAirflow has gained adoption among developers and data scientists alike thanks to its focus on configuration as code.вЂќ вЂњApache Airflow has quickly become the de facto standard for workflow orchestration,вЂќ said Bolke de Bruin, vice president of Apache Airflow. The Apache Software FoundationвЂ™s latest top-level project, Airflow, workflow automation and scheduling stem for Big Data processing pipelines, already is in use at more than 200 organizations, including Adobe, Airbnb, Paypal, Square, Twitter and United Airlines.
