Depending on your version of Airflow: For Airflow 2, the stable REST API is already enabled by default. If your environment has the stable API disabled, then enable the stable REST API. For Airflow 1, enable the experimental REST API. Allow API calls to Airflow REST API using Webserver Access … Two “real” methods for authentication are currently supported for the API. To enabled Password authentication, set the following in the configuration: [ api] auth_backend = airflow.contrib.auth.backends.password_auth. It’s usage is similar to the Password Authentication used for the Web interface. Params. Params enable you to provide runtime configuration to tasks. You can configure default Params in your DAG code and supply additional Params, or overwrite Param values, at runtime when you trigger a DAG. Param values are validated with JSON Schema. For scheduled DAG runs, default Param values are used. 1. Airflow dags are python objects, so you can create a dags factory and use any external data source (json/yaml file, a database, NFS volume, ...) as source for your dags. Here are the steps to achieve your goal: create a python script in your dags folder (assume its name is dags_factory.py)

Apache Airflow is an open-source workflow management platform for data engineering pipelines.

HttpOperator. Use the HttpOperator to call HTTP requests and get the response text back. For historical reasons, configuring HTTPS connectivity via HTTP operator is, well, difficult and counter-intuitive. The Operator defaults to http protocol and you can change the schema used by the operator via scheme connection attribute.

Variables are Airflow’s runtime configuration concept - a general key/value store that is global and can be queried from your tasks, and easily set via Airflow’s user interface, or bulk-uploaded as a JSON file. To use them, just import and call get on the Variable model:

Configuration Reference. This page contains the list of all the available Airflow configurations that you can set in airflow.cfg file or using environment variables. Use the same configuration across all the Airflow components. While each component does not require all, some configurations need to be same otherwise they would not work as expected.

Using Airflow plugins can be a way for companies to customize their Airflow installation to reflect their ecosystem. Plugins can be used as an easy way to write, share and activate new sets of features. There’s also a need for a set of more complex applications to interact with different flavors of data and metadata. Examples: To configure SMTP settings, checkout the SMTP section in the standard configuration. If you do not want to store the SMTP credentials in the config or in the environment variables, you can create a connection called smtp_default of Email type, or choose a custom connection name and set the email_conn_id with its name in the configuration & store …How to reduce airflow dag scheduling latency in production?
