======== AWS Glue

AWS Glue <https://aws.amazon.com/glue/>__ is a serverless data integration service that makes it easy to discover, prepare, and combine data for analytics, machine learning, and application development. AWS Glue provides all the capabilities needed for data integration so that you can start analyzing your data and putting it to use in minutes instead of months.

Prerequisite Tasks

.. include:: ../_partials/prerequisite_tasks.rst

Generic Parameters

.. include:: ../_partials/generic_parameters.rst

Operators

.. _howto/operator:GlueCrawlerOperator:

Create an AWS Glue crawler

AWS Glue Crawlers allow you to easily extract data from various data sources. To create a new AWS Glue Crawler or run an existing one you can use :class:~airflow.providers.amazon.aws.operators.glue_crawler.GlueCrawlerOperator.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue.py :language: python :dedent: 4 :start-after: [START howto_operator_glue_crawler] :end-before: [END howto_operator_glue_crawler]

.. note:: The AWS IAM role included in the config needs access to the source data location (e.g. s3:PutObject access if data is stored in Amazon S3) as well as the AWSGlueServiceRole policy. See the References section below for a link to more details.

.. _howto/operator:GlueJobOperator:

Submit an AWS Glue job

To submit a new AWS Glue job you can use :class:~airflow.providers.amazon.aws.operators.glue.GlueJobOperator.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue.py :language: python :dedent: 4 :start-after: [START howto_operator_glue] :end-before: [END howto_operator_glue]

.. note:: The same AWS IAM role used for the crawler can be used here as well, but it will need policies to provide access to the output location for result data.

.. _howto/operator:GlueDataQualityOperator:

Create an AWS Glue Data Quality

AWS Glue Data Quality allows you to measure and monitor the quality of your data so that you can make good business decisions. To create a new AWS Glue Data Quality ruleset or update an existing one you can use :class:~airflow.providers.amazon.aws.operators.glue.GlueDataQualityOperator.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue_data_quality.py :language: python :dedent: 4 :start-after: [START howto_operator_glue_data_quality_operator] :end-before: [END howto_operator_glue_data_quality_operator]

.. _howto/operator:GlueDataQualityRuleSetEvaluationRunOperator:

Start a AWS Glue Data Quality Evaluation Run

To start a AWS Glue Data Quality ruleset evaluation run you can use :class:~airflow.providers.amazon.aws.operators.glue.GlueDataQualityRuleSetEvaluationRunOperator.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue_data_quality.py :language: python :dedent: 4 :start-after: [START howto_operator_glue_data_quality_ruleset_evaluation_run_operator] :end-before: [END howto_operator_glue_data_quality_ruleset_evaluation_run_operator]

.. _howto/operator:GlueDataQualityRuleRecommendationRunOperator:

Start a AWS Glue Data Quality Recommendation Run

To start a AWS Glue Data Quality rule recommendation run you can use :class:~airflow.providers.amazon.aws.operators.glue.GlueDataQualityRuleRecommendationRunOperator.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue_data_quality_with_recommendation.py :language: python :dedent: 4 :start-after: [START howto_operator_glue_data_quality_rule_recommendation_run] :end-before: [END howto_operator_glue_data_quality_rule_recommendation_run]

Sensors

.. _howto/sensor:GlueCrawlerSensor:

Wait on an AWS Glue crawler state

To wait on the state of an AWS Glue crawler execution until it reaches a terminal state you can use :class:~airflow.providers.amazon.aws.sensors.glue_crawler.GlueCrawlerSensor.

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue.py :language: python :dedent: 4 :start-after: [START howto_sensor_glue_crawler] :end-before: [END howto_sensor_glue_crawler]

.. _howto/sensor:GlueJobSensor:

Wait on an AWS Glue job state

To wait on the state of an AWS Glue Job until it reaches a terminal state you can use :class:~airflow.providers.amazon.aws.sensors.glue.GlueJobSensor

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue.py :language: python :dedent: 4 :start-after: [START howto_sensor_glue] :end-before: [END howto_sensor_glue]

.. _howto/sensor:GlueDataQualityRuleSetEvaluationRunSensor:

Wait on an AWS Glue Data Quality Evaluation Run

To wait on the state of an AWS Glue Data Quality RuleSet Evaluation Run until it reaches a terminal state you can use :class:~airflow.providers.amazon.aws.sensors.glue.GlueDataQualityRuleSetEvaluationRunSensor

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue_data_quality.py :language: python :dedent: 4 :start-after: [START howto_sensor_glue_data_quality_ruleset_evaluation_run] :end-before: [END howto_sensor_glue_data_quality_ruleset_evaluation_run]

.. _howto/sensor:GlueDataQualityRuleRecommendationRunSensor:

Wait on an AWS Glue Data Quality Recommendation Run

To wait on the state of an AWS Glue Data Quality recommendation run until it reaches a terminal state you can use :class:~airflow.providers.amazon.aws.sensors.glue.GlueDataQualityRuleRecommendationRunSensor

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue_data_quality_with_recommendation.py :language: python :dedent: 4 :start-after: [START howto_sensor_glue_data_quality_rule_recommendation_run] :end-before: [END howto_sensor_glue_data_quality_rule_recommendation_run]

.. _howto/sensor:GlueCatalogPartitionSensor:

Wait on an AWS Glue Catalog Partition

To wait for a partition to show up in AWS Glue Catalog until it reaches a terminal state you can use :class:~airflow.providers.amazon.aws.sensors.glue_catalog_partition.GlueCatalogPartitionSensor

.. exampleinclude:: /../../amazon/tests/system/amazon/aws/example_glue.py :language: python :dedent: 4 :start-after: [START howto_sensor_glue_catalog_partition] :end-before: [END howto_sensor_glue_catalog_partition]
