Aircal

Aircal is a library that exports future DAG runs as events to Google Calendar.

Having DAG run as events in the calendar may help you:

• visualize the utilization of your airflow workers to better spread your jobs
• determine when a certain DAG should be finished to monitor the service.

The library will also observe the changes to your DAGs and synchronize it with the calendar:

• add runs for the freshly added DAGs
• change start and/or end time when an existing DAG changes the schedule (or the execution time changes significantly)
• delete run events when a DAG is removed (or paused)

Tip: run the sync script regularly, perhaps, with you know, Airflow :)

The library only support DAG schedules that use the standard cron syntax. The rest will be ignored (with a warning).

Warning: This is an beta stage software. Expect occassional bugs and rough edges (PR welcome).

Installation & setup

pip install aircal

Alternatively you can clone the repo and install it from there:

pip install -e .

Google API credentials are required to create events in the calendar. You can obtain them here. Store credentials.json into a directory accessible by your code.

The library is modifying and deleting calendar events. I highly recommend creating a new calendar to be used by this software: "add calendar" -> "create new calendar" in Google calendar settings.

Usage

See example.py for an example of the potential pipeline that can be run on the regular intervals.
