Description

Airflow is a platform to programmatically author, schedule, and monitor workflows.

When workflows are defined as code, they become more maintainable, versionable, testable, and collaborative.

Use Airflow to author workflows as directed acyclic graphs (DAGs) of tasks. The Airflow scheduler executes your tasks on an array of workers while following the specified dependencies. Rich command line utilities make performing complex surgeries on DAGs a snap. The rich user interface makes it easy to visualize pipelines running in production, monitor progress, and troubleshoot issues when needed.

Requirements

Apache Airflow is tested with:

Master version (2.0.0dev)

  • Python versions: 3.6, 3.7
  • Postgres DB: 9.6 10
  • MySQL DB: 5.7
  • Sqlite - latest stable (it is used mainly for development purpose)

Stable version (1.10.9)

  • Python versions: 2.7, 3.5, 3.6, 3.7
  • Postgres DB: 9.6 10
  • MySQL DB: 5.6, 5.7
  • Sqlite - latest stable (it is used mainly for development purpose)

Getting started

Please visit the Airflow Platform documentation (latest stable release) for help with installing Airflow, getting a quick start, or a more complete tutorial.

Documentation of GitHub master (latest development branch): ReadTheDocs Documentation

Beyond the Horizon

Airflow is not a data streaming solution. Tasks do not move data from one to the other (though tasks can exchange metadata!). Airflow is not in the Spark Streaming or Storm space, it is more comparable to Oozie or Azkaban.

Workflows are expected to be mostly static or slowly changing. You can think of the structure of the tasks in your workflow as slightly more dynamic than a database structure would be. Airflow workflows are expected to look similar from a run to the next, this allows for clarity around unit of work and continuity.

Principles

  • Dynamic: Airflow pipelines are configuration as code (Python), allowing for dynamic pipeline generation. This allows for writing code that instantiates pipelines dynamically.
  • Extensible: Easily define your own operators, executors and extend the library so that it fits the level of abstraction that suits your environment.
  • Elegant: Airflow pipelines are lean and explicit. Parameterizing your scripts is built into the core of Airflow using the powerful Jinja templating engine.
  • Scalable: Airflow has a modular architecture and uses a message queue to orchestrate an arbitrary number of workers.

User Interface

  • DAGs: Overview of all DAGs in your environment.

  • Tree View: Tree representation of a DAG that spans across time.

  • Graph View: Visualization of a DAG's dependencies and their current status for a specific run.

  • Task Duration: Total time spent on different tasks over time.

  • Gantt View: Duration and overlap of a DAG.

  • Code View: Quick way to view source code of a DAG.

Using hooks and Operators from "master" in Airflow 1.10

Currently stable versions of Apache Airflow are released in 1.10.* series. We are working on the future, major version of Airflow from the 2.0.* series. It is going to be released in in 2020. However the exact time of release depends on many factors and is yet unknown. We have already a lot of changes in the hooks/operators/sensors for many external systems and they are not used because they are part of the master/2.0 release.

In the Airflow 2.0 - following AIP-21 "change in import paths" all the non-core operators/hooks/sensors of Apache Airflow have been moved to the "airflow.providers" package. This opened a possibility to use the operators from Airflow 2.0 in Airflow 1.10 - with the constraint that those packages can only be used in python3.6+ environment.

Therefore we decided to prepare and release backport packages that can be installed for older Airflow versions. Those backport packages are released more frequently. Users do not have to upgrade their Airflow version to use those packages. There are a number of changes between Airflow 2.0 and 1.10.* - documented in [UPDATING.md](../UPDATING.md). With backported providers package users can migrate their DAGs to the new providers package incrementally and once they convert to the new operators/sensors/hooks they can seamlessly migrate their environments to Airflow 2.0.

More information about the status and releases of the back-ported packages are available at Backported providers package page

Dependencies between packages are stored in airflow/providers/dependencies.json. See CONTRIBUTING.rst
