In the upcoming video, Ajay will introduce you to the concept of Airflow variables. So, in the video, you learnt about Airflow variables.
Let’s take a look at some of the highlights:
- Variables are key-value stores in Airflow’s metadata database.
- They are a generic way to store and retrieve arbitrary content or settings within Airflow.
- Apart from variables, you can also use Jinja templating by making use of reference parameters such as {{ ds }} (for execution date ) and {{ run_id }} (the id of the current run).
- They are accessible through the Airflow UI (Admin-> Variables).
- Sample use of a variable is given below.
In the next segment, you will understand another advanced concept in airflow-XComs.
