#Airflow 2.0 github upgrade#

Status: WIP - we will continue releasing updates to upgrade check separately from 2.0 release. To make it easier for users to upgrade from 1.10 to 2.0, we should create a single upgrade-check command in 1.10 that checks the common incompatibilities. We released packages that will allow us to use operators/hooks from Airflow 2.0 in Airflow 1.10. In all steps, the user is assisted by migration guides and runtime warnings. Once the migration is successful the user can happily use Airflow 2.0.In the next step, the user installs the latest version of Airflow and will migrate the database - airflow db upgrade.This command checks for common incompatibility problems. When the user is on the latest Airflow 1.10 release, they can use the airflow upgrade-check command to see if they can migrate to the new Airflow version.

When the user is using Python 3.6+, they can start to use new operators and hooks from Python 3.6 thanks to backport packages.

When the user is using Python 2.7, they need to migrate to Python 3.6+.

We discussed the migration path that a user should do in order to start using Airflow 2.0 easily The 2.0 release of the Airflow is a significant upgrade and includes substantial major changes, For this reason, we must take additional steps to facilitate migration.

More information is available on the wiki:Īll tasks are collected in "Airflow 2.0rc1" milestone for RC1 and all remaining "administrative" tasks that do not require release are in "Airflow 2.0" milestone RoadmapĪpart from defining the scope of work, we should also complete these tasks. This will make it more transparent and friendly.

This ticket should not describe individual changes to the code but summarize information that active community members know, but new community members don't know but want to know. This is a meta-ticket, so I would ask committers and PMC members to keep it up-to-date so that everyone has easy access to up-to-date information. This new feature enables high availability, scalability and greater performance.I am creating this ticket to help follow this process and coordinate our activities. SchedulerĪ new feature for Airflow 2.0 is the option to provide multiple schedulers. More information here.įor our purposes we have chosen a Postgres backend.

Web server - HTTP Server provides access to DAG/task status informationįor the Metadata Database a number of databases can be chosen.

Executor - Works closely with the Scheduler to determine what resources are needed to complete the tasks as they are queued.

Scheduler - Reads from the Metadata database and is responsible for adding the necessary tasks to the queue.

Metadata Database - Contains information about the status of tasks, DAGs, Variables, connections, etc.

We also make use of the docker compose tool to define and run multiple Docker container applications.

Architecture Show/Hide DetailsĪll applications are packaged up using Docker to isolate the software from its env so that it works in different development environments. Place your dag files within dags/ and your plugins within plugins/.
