Google Cloud Data Catalog Operators
=======================================

The `Data Catalog <https://cloud.google.com/data-catalog>`__ is a fully managed and scalable metadata
management service that allows organizations to quickly discover, manage and understand all their data in
Google Cloud. It offers:

* A simple and easy to use search interface for data discovery, powered by the same Google search technology that
  supports Gmail and Drive
* A flexible and powerful cataloging system for capturing technical and business metadata
* An auto-tagging mechanism for sensitive data with DLP API integration

Managing an entries
^^^^^^^^^^^^^^^^^^^

Operators uses a :class:`~google.cloud.datacatalog_v1beta1.types.Entry` for representing entry

Getting an entry
""""""""""""""""

Getting an entry is performed with the
:class:`~airflow.providers.google.cloud.operators.datacatalog.CloudDataCatalogGetEntryOperator` and
:class:`~airflow.providers.google.cloud.operators.datacatalog.CloudDataCatalogLookupEntryOperator`
operators.

The ``CloudDataCatalogGetEntryOperator`` use Project ID, Entry Group ID, Entry ID to get the entry.

.. exampleinclude:: /../../tests/system/providers/google/datacatalog/example_datacatalog_entries.py

You can use :ref:`Jinja templating <concepts:jinja-templating>` with
:template-fields:`airflow.providers.google.cloud.operators.datacatalog.CloudDataCatalogGetEntryOperator`
parameters which allows you to dynamically determine values.

The result is saved to :ref:`XCom <concepts:xcom>`, which allows it to be used by other operators.
