Airflow Render Template

Airflow Render Template - Even though params can use a variety of types, the default behaviour of templates is to provide your task with a string. Templates and macros in apache airflow allow passing data to your dags at runtime. You can see in the code base that airflow invokes render_templates before it invokes pre_execute() and before it invokes execute(). Given a dag_id , task_id , and random execution_date , the command output is similar to the following example: Imagine that you want to execute an sql request with the execution date of your dag. Which variables and functions are available when templating; How to render templates to strings and native python code This means that this step happens when the task is running on a worker. Or what if you need to know when the next dag run will be? You can change this by setting.
