Google Cloud Looker Operators

Looker is a business intelligence software and big data analytics platform that helps you explore, analyze and share real-time business analytics easily.

Looker has a Public API and associated SDK clients in different languages, which allow programmatic access to the Looker data platform.

For more information visit Looker API documentation <https://docs.looker.com/reference/api-and-integration>_.

Prerequisite Tasks

To use these operators, you must do a few things:

Install API libraries via pip.

.. code-block:: bash

pip install 'apache-airflow[google]'

Detailed information is available for :doc:Installation <apache-airflow:installation/index>.

Setup a Looker connection in Airflow. You can check :doc:apache-airflow:howto/connection and :doc:/connections/gcp_looker

Start a PDT materialization job

To submit a PDT materialization job to Looker you need to provide a model and view name.

The job configuration can be submitted in synchronous (blocking) mode by using: :class:~airflow.providers.google.cloud.operators.looker.LookerStartPdtBuildOperator.

.. exampleinclude:: /../../google/tests/system/google/cloud/looker/example_looker.py :language: python :dedent: 4 :start-after: [START how_to_cloud_looker_start_pdt_build_operator] :end-before: [END how_to_cloud_looker_start_pdt_build_operator]

Alternatively, the job configuration can be submitted in asynchronous mode by using: :class:~airflow.providers.google.cloud.operators.looker.LookerStartPdtBuildOperator and :class:~airflow.providers.google.cloud.sensors.looker.LookerCheckPdtBuildSensor.

.. exampleinclude:: /../../google/tests/system/google/cloud/looker/example_looker.py :language: python :dedent: 4 :start-after: [START cloud_looker_async_start_pdt_sensor] :end-before: [END cloud_looker_async_start_pdt_sensor]

There are more arguments to provide in the jobs than the examples show. For the complete list of arguments take a look at Looker operator arguments at :class:airflow.providers.google.cloud.operators.looker.LookerStartPdtBuildOperator
