Apache Airflow Custom Operator Development: A Comprehensive Guide Apache Airflow is a leading open-source platform for orchestrating workflows, and its extensibility Thanks, trying this now. Here is the data pipeline we will use: from airflow import DAG from airflow. For Airflow context variables make sure that you either have access 1 BashOperator is Jinja templated, so params can be passed as dictionary. (templated) Effortlessly establish an Airflow Postgres connection. This extensibility is one of the many While I understand how that works for pythonoperator, but can templating be used for parameterizing operators? Are there certain fields that are rendered and others aren't? Params are arguments which you can pass to an Airflow DAG or task at runtime and are stored in the Airflow context dictionary for each DAG run. The operator support this but I'm not sure what to do with the parameter the SQL is needed. Usually, I pass variables such as table/database names, etc Templates reference ¶ Variables, macros and filters can be used in templates (see the Jinja Templating section) The following come for free out of the box with Airflow.
