LookerStartPdtBuildOperator

Submits a PDT materialization job to Looker.
class airflow.providers.google.cloud.operators.looker.LookerStartPdtBuildOperator(looker_conn_id, model, view, query_params=None, asynchronous=False, cancel_on_kill=True, wait_time=10, wait_timeout=None, **kwargs)[source]

Bases: airflow.models.BaseOperator

Submits a PDT materialization job to Looker.

Parameters

  • looker_conn_id (str) -- Required. The connection ID to use connecting to Looker.

  • model (str) -- Required. The model of the PDT to start building.

  • view (str) -- Required. The view of the PDT to start building.

  • query_params (Optional[Dict]) -- Optional. Additional materialization parameters.

  • asynchronous (bool) -- Optional. Flag indicating whether to wait for the job to finish or return immediately. This is useful for submitting long running jobs and waiting on them asynchronously using the LookerCheckPdtBuildSensor

  • cancel_on_kill (bool) -- Optional. Flag which indicates whether cancel the hook's job or not, when on_kill is called.

  • wait_time (int) -- Optional. Number of seconds between checks for job to be ready. Used only if asynchronous is False.

  • wait_timeout (Optional[int]) -- Optional. How many seconds wait for job to be ready. Used only if asynchronous is False.

execute(self, context)[source]

This is the main method to derive when creating an operator. Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.

on_kill(self)[source]

Override this method to cleanup subprocesses when a task instance gets killed. Any use of the threading, subprocess or multiprocessing module within an operator needs to be cleaned up or it will leave ghost processes behind.
