SQLExecuteQueryOperator to connect to Vertica

Use the :class:SQLExecuteQueryOperator <airflow.providers.common.sql.operators.sql> to execute Vertica commands in a Vertica <https://www.vertica.com/documentation/>__ database.

.. note:: If you previously used other legacy operators to handle Vertica interactions, you can now use SQLExecuteQueryOperator for both stored procedures and raw SQL execution.

Using the Operator ^^^^^^^^^^^^^^^^^^

Use the conn_id argument to connect to your Vertica instance where the connection metadata is structured as follows:

.. list-table:: Vertica Airflow Connection Metadata :widths: 25 25 :header-rows: 1

- Parameter
- Input
- Host: string
- Vertica database hostname or container name (if running in Docker network)
- Schema: string
- Schema to execute SQL operations on by default
- Login: string
- Vertica database user (often dbadmin if using community Docker image)
- Password: string
- Vertica database user password
- Port: int
- Vertica database port (default: 5433)
- Extra: JSON
- Additional connection configuration (e.g. TLS settings): {"tlsmode": "disable"}

An example usage of the SQLExecuteQueryOperator to connect to Vertica is as follows:

.. exampleinclude:: /../../vertica/tests/system/vertica/example_vertica.py :language: python :start-after: [START howto_operator_vertica] :end-before: [END howto_operator_vertica]

Reference ^^^^^^^^^

For further information, look at:

Vertica Documentation <https://www.vertica.com/documentation/>__

.. note::

Parameters given via SQLExecuteQueryOperator() take first-place priority relative to parameters set via the Airflow connection metadata (such as schema, login, password, etc).
