<span class="sd">Example Airflow DAG that demonstrates interactions with Google Cloud Transfer.</span>
<span class="sd">This DAG relies on the following OS environment variables</span>
<span class="sd">* GCP_PROJECT_ID - Google Cloud Project to use for the Google Cloud Transfer Service.</span>
<span class="sd">* GCP_DESCRIPTION - Description of transfer job</span>
<span class="sd">* GCP_TRANSFER_SOURCE_AWS_BUCKET - Amazon Web Services Storage bucket from which files are copied.</span>
<span class="sd"> .. warning::</span>
<span class="sd"> You need to provide a large enough set of data so that operations do not execute too quickly.</span>
<span class="sd"> Otherwise, DAG will fail.</span>
<span class="sd">* GCP_TRANSFER_FIRST_TARGET_BUCKET - Google Cloud Storage bucket to which files are copied from AWS.</span>
<span class="sd"> It is also a source bucket in next step</span>
<span class="sd">* GCP_TRANSFER_SECOND_TARGET_BUCKET - Google Cloud Storage bucket bucket to which files are copied</span>
<span class="sd">* WAIT_FOR_OPERATION_POKE_INTERVAL - interval of what to check the status of the operation</span>
<span class="sd"> A smaller value than the default value accelerates the system test and ensures its correct execution with</span>
<span class="sd"> smaller quantities of files in the source bucket</span>
<span class="sd"> Look at documentation of :class:`~airflow.operators.sensors.BaseSensorOperator` for more information</span>
