This was chosen to follow suit with the core Apache Airflow project. Unless otherwise specified, everything in the airflow-plugins org is by default licensed under Apache 2.0. Example DAGsĪll example DAGs that use the plugins can be found in the Example Airflow DAGs repo. General guidelines for how to get your plugin into shape can be found here. If you have a plugin that you've built or nefariously acquired (no judgement), we'd be more than happy to have it added to the org. The GCP Base Hook solves this in Airflow 1.9 by allowing the contents of the keyfile to be put in an Airflow connection object but, for those still using 1.8 and lower, we've put together a quick tutorial on how to used modified hooks as a workaround. Example tutorials currently available include:īecause Google Cloud Platform's authentication requires a keyfile for a service account, accessing tools like BigQuery from a containerized environment (without persistent local storage) can be somewhat complex. Tutorials can be found in the Tutorials folder. Generally one repo is made per plugin with related operators and hooks are grouped together in one plugin when possible. If your URLs aren't being generated correctly (usually they'll start with instead of the correct hostname), you may need to set the webserver base_url config.Getting Started with Airflow Plugins Table of ContentsĪ full list of available plugins can be found here. Smart sensors the smart sensors introduced in Airflow 2.0 have significantly improved the overall efficiency of the. ![]() REST API after years of using Airflow’s Experimental API, your data engineers will surely be relieved that Airflow 2.0 provides them with a full REST API. Like in ingestion, we support a Datahub REST hook and a Kafka-based hook. The new scheduler works faster and is highly scalable. You can check the current configuration with the airflow config list command. If you look at our recent quick-start docker compose, you will see that you can add a separate airflow-cli docker compose (it will be released tomorrow / day after with 2.1. In order to use this example, you must first configure the Datahub hook. For Airflow versions > 2.2.1, < 2.3.0 Airflow’s built in defaults took precedence over command and secret key in airflow.cfg in some circumstances. lineage_emission_dag.py - emits lineage using the DatahubEmitterOperator.Note that configuration issues will still throw exceptions.Įmitting lineage via a separate operator We strongly recommend that all users upgrading to Airflow 2.0, first upgrade to Airflow 1.10.15 and test their Airflow deployment and only then upgrade to. graceful_exceptions (defaults to true): If set to true, most runtime errors in the lineage backend will be suppressed and will not cause the overall task to fail. Airflow 1.10.15 includes support for various features that have been backported from Airflow 2.0 to make it easy for users to test their Airflow environment before upgrading to Airflow 2.0.capture_executions (defaults to false): If true, it captures task runs as DataHub DataProcessInstances.capture_tags_info (defaults to true): If true, the tags field of the DAG will be captured as DataHub tags.capture_ownership_info (defaults to true): If true, the owners field of the DAG will be capture as a DataHub corpuser.cluster (defaults to "prod"): The "cluster" to associate Airflow DAGs and tasks with.datahub_conn_id (required): Usually datahub_rest_default or datahub_kafka_default, depending on what you named the connection in step 1.To be able to expose Airflow metrics to Prometheus you will need install a plugin, one option is. ![]() In the task logs, you should see Datahub related log messages like: For example, using airflow 2.0.1, with python 3.6.
