Update version in docs/start/docker*
Apache Airflow (or simply 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.
Table of contents
Airflow works best with workflows that are mostly static and slowly changing. When DAG structure is similar from one run to the next, it allows for clarity around unit of work and continuity. Other similar projects include Luigi, Oozie and Azkaban.
Airflow is commonly used to process data, but has the opinion that tasks should ideally be idempotent (i.e. results of the task will be the same, and will not create duplicated data in a destination system), and should not pass large quantities of data from one task to the next (though tasks can pass metadata using Airflow's Xcom feature). For high-volume, data-intensive tasks, a best practice is to delegate to external services that specialize on that type of work.
Airflow is not a streaming solution, but it is often used to process real-time data, pulling data off streams in batches.
Apache Airflow is tested with:
Master version (dev) | Stable version (2.0.1) | Previous version (1.10.14) | |
---|---|---|---|
Python | 3.6, 3.7, 3.8 | 3.6, 3.7, 3.8 | 2.7, 3.5, 3.6, 3.7, 3.8 |
PostgreSQL | 9.6, 10, 11, 12, 13 | 9.6, 10, 11, 12, 13 | 9.6, 10, 11, 12, 13 |
MySQL | 5.7, 8 | 5.7, 8 | 5.6, 5.7 |
SQLite | 3.15.0+ | 3.15.0+ | 3.15.0+ |
Kubernetes | 1.20, 1.19, 1.18 | 1.20, 1.19, 1.18 | 1.18, 1.17, 1.16 |
Note: MySQL 5.x versions are unable to or have limitations with running multiple schedulers -- please see the “Scheduler” docs. MariaDB is not tested/recommended.
Note: SQLite is used in Airflow tests. Do not use it in production. We recommend using the latest stable version of SQLite for local development.
As of Airflow 2.0 we agreed to certain rules we follow for Python support. They are based on the official release schedule of Python, nicely summarized in the Python Developer's Guide
We finish support for python versions when they reach EOL (For python 3.6 it means that we will remove it from being supported on 23.12.2021).
The “oldest” supported version of Python is the default one. “Default” is only meaningful in terms of “smoke tests” in CI PRs which are run using this default version.
We support a new version of Python after it is officially released, as soon as we manage to make it works in our CI pipeline (which might not be immediate) and release a new version of Airflow (non-Patch version) based on this CI set-up.
Visit the official Airflow website documentation (latest stable release) for help with installing Airflow, getting started, or walking through a more complete tutorial.
Note: If you're looking for documentation for master branch (latest development branch): you can find it on s.apache.org/airflow-docs.
For more information on Airflow's Roadmap or Airflow Improvement Proposals (AIPs), visit the Airflow Wiki.
Official Docker (container) images for Apache Airflow are described in IMAGES.rst.
We publish Apache Airflow as apache-airflow
package in PyPI. Installing it however might be sometimes tricky because Airflow is a bit of both a library and application. Libraries usually keep their dependencies open and applications usually pin them, but we should do neither and both at the same time. We decided to keep our dependencies as open as possible (in setup.py
) so users can install different versions of libraries if needed. This means that from time to time plain pip install apache-airflow
will not work or will produce unusable Airflow installation.
In order to have repeatable installation, however, introduced in Airflow 1.10.10 and updated in Airflow 1.10.12 we also keep a set of “known-to-be-working” constraint files in the orphan constraints-master
, constraints-2-0
and constraints-1-10
branches. We keep those “known-to-be-working” constraints files separately per major/minor python version. You can use them as constraint files when installing Airflow from PyPI. Note that you have to specify correct Airflow tag/version/branch and python versions in the URL.
NOTE!!!
On November 2020, new version of PIP (20.3) has been released with a new, 2020 resolver. This resolver might work with Apache Airflow as of 20.3.3, but it might lead to errors in installation. It might depend on your choice of extras. In order to install Airflow reliably, you might need to either downgrade pip to version 20.2.4 pip install --upgrade pip==20.2.4
or, in case you use Pip 20.3, you might need to add option] --use-deprecated legacy-resolver
to your pip install command. While pip 20.3.3
solved most of the teething
problems of 20.3, this note will remain here until we set pip 20.3
as official version in our CI pipeline where we are testing the installation as well. Due to those constraints, only pip
installation is currently officially supported.
While they are some successes with using other tools like poetry or pip-tools, they do not share the same workflow as pip
- especially when it comes to constraint vs. requirements management. Installing via Poetry
or pip-tools
is not currently supported.
If you wish to install airflow using those tools you should use the constraint files and convert them to appropriate format and workflow that your tool requires.
pip install apache-airflow==2.0.1 \ --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.0.1/constraints-3.7.txt"
pip install apache-airflow[postgres,google]==2.0.1 \ --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.0.1/constraints-3.7.txt"
For information on installing provider packages check providers.
Apache Airflow is an Apache Software Foundation (ASF) project, and our official source code releases:
Following the ASF rules, the source packages released must be sufficient for a user to build and test the release provided they have access to the appropriate platform and tools.
There are other ways of installing and using Airflow. Those are “convenience” methods - they are not “official releases” as stated by the ASF Release Policy
, but they can be used by the users who do not want to build the software themselves.
Those are - in the order of most common ways people install Airflow:
pip
tooldocker
tool, use them in Kubernetes, Helm Charts, docker-compose
, docker swarm
etc. You can read more about using, customising, and extending the images in the Latest docs, and learn details on the internals in the IMAGES.rst document.All those artifacts are not official releases, but they are prepared using officially released sources. Some of those artifacts are “development” or “pre-release” ones, and they are clearly marked as such following the ASF Policy.
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.

Airflow is the work of the community, but the core committers/maintainers are responsible for reviewing and merging PRs as well as steering conversation around new feature requests. If you would like to become a maintainer, please review the Apache Airflow committer requirements.
