#DATA PIPELINES WITH APACHE AIRFLOW HOW TO#

These include hints for getting efficient quickly with Airflow, approaches to structure workflows, integrating it in an enterprise landscape, writing plugins and extentions, and maintaining it in productive environment. Based on several years of productive usage, we briefly summarize the core concepts of Airflow, and detail in-depth on lessons learned and best practices from our experience. Features which differentiate Airflow from similar projects like Apache Oozie, Luigi or Azkaban include (i) its pluggable architecture with several extension points (ii) the programmatic approach of 'workflow is code' and (iii) its tight relationship with the the Python as well as the Big Data Analytics Ecosystem. perform feature extraction on a given dataset, apply an existing deep learning model to it, and write the results in the backend of a microserviceĪpache Airflow is an open-source Python project developed by AirBnB which facilitates the programmatic definition of such pipelines.

Importing several files with different formats into a Hadoop platform, perform data cleansing, and training a machine learning model on the result.A widely adopted notion for this process is a 'data pipeline' - which consists mainly of a set of 'operators' which perform a particular action on data, with the possibility to specify dependencies among those. Based on 2+ years of productive experience, we summarize its core concepts, detail on lessons learned and set it in context with the Big Data Analytics Ecosystem.Ĭreating, orchestrating and running multiple data processing or analysis steps may cover a substantial portion of a Data Engineer and Data Scientist business. He is most experienced in tools around the Hadoop Ecosystem like Apache Hive and Spark, and has hands-on experience with productionizing analytical applications.Īpache Airflow is an Open-Source python project which facilitates an intuitive programmatic definition of analytical data pipelines. In this time, he was involved in several projects concerned with establishing analytical data platforms in various companies. Since 2012 he is working as a Big Data Engineer at Inovex GmbH. Bas is a committer, and both Bas and Julian are active contributors to Apache Airflow.Dominik Benz Benz holds a PhD from the University of Kassel in the field of Data Mining on the Social Web.

Bas Harenslak and Julian de Ruiter are data engineers with extensive experience using Airflow to develop pipelines for major companies including Heineken, Unilever, and. Airflow streamlines the whole process, giving you one tool for programmatically developing and monitoring batch data pipelines, and integrating all the pieces you use in your data stack. About the technology Data pipelines are used to extract, transform and load data to and from multiple sources, routing it wherever it's needed - whether that's visualisation tools, business intelligence dashboards, or machine learning models. Key Features Framework foundation and best practices Airflow's execution and dependency system Testing Airflow DAGs Running Airflow in production For data-savvy developers, DevOps and data engineers, and system administrators with intermediate Python skills. With complete coverage of both foundational and lesser-known features, when you're done you'll be set to start using Airflow for seamless data pipeline development and management.

Data Pipelines with Apache Airflow teaches you the ins-and-outs of the Directed Acyclic Graphs (DAGs) that power Airflow, and how to write your own DAGs to meet the needs of your projects. Data Pipelines with Apache Airflow takes you through best practices for creating pipelines for multiple tasks, including data lakes, cloud deployments, and data science. Airflow lets you schedule, restart, and backfill pipelines, and its easy-to-use UI and workflows with Python scripting has users praising its incredible flexibility. Pipelines can be challenging to manage, especially when your data has to flow through a collection of application components, servers, and cloud services.
