SQLExecuteQueryOperator to connect to Apache Druid

Use the :class:SQLExecuteQueryOperator<airflow.providers.common.sql.operators.sql.SQLExecuteQueryOperator> to execute SQL queries against an Apache Druid <https://druid.apache.org/>__ cluster.

.. note:: Previously, a dedicated operator for Druid might have been used. After deprecation, please use the SQLExecuteQueryOperator instead.

.. note:: Make sure you have installed the apache-airflow-providers-apache-druid package to enable Druid support.

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

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

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

• • Parameter
  • Input
• • Host: string
  • Druid broker hostname or IP address
• • Schema: string
  • Not applicable (leave blank)
• • Login: string
  • Not applicable (leave blank)
• • Password: string
  • Not applicable (leave blank)
• • Port: int
  • Druid broker port (default: 8082)
• • Extra: JSON
  • Additional connection configuration, such as: {"endpoint": "/druid/v2/sql/", "method": "POST", "ssl_verify_cert": false}

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

.. exampleinclude:: /../tests/system/apache/druid/example_druid.py :language: python :start-after: [START howto_operator_druid] :end-before: [END howto_operator_druid]

Reference ^^^^^^^^^ For further information, see:

• Apache Druid Documentation <https://druid.apache.org/docs/latest/>__

.. note:: Parameters provided directly via SQLExecuteQueryOperator() take precedence over those specified in the Airflow connection metadata (such as schema, login, password, etc).
