Amazon SQS Operators
====================

`Amazon Simple Queue Service (SQS) <https://aws.amazon.com/sqs/>`__  is a fully managed message queuing
service that enables you to decouple and scale microservices, distributed systems, and serverless
applications. SQS eliminates the complexity and overhead associated with managing and operating
message-oriented middleware, and empowers developers to focus on differentiating work. Using SQS, you
can send, store, and receive messages between software components at any volume, without losing messages
or requiring other services to be available.

Prerequisite Tasks

In the following example, the task "publish_to_queue" publishes a message containing
the task instance and the execution date to a queue with a default name of ``Airflow-Example-Queue``.

.. exampleinclude:: /../../airflow/providers/amazon/aws/example_dags/example_sqs.py
    :language: python
    :start-after: [START howto_sqs_operator]
    :end-before: [END howto_sqs_operator]

.. _howto/operator:SqsSensor:

Amazon SQS Sensor
"""""""""""""""""

To read messages from an Amazon SQS queue until exhausted use the
:class:`~airflow.providers.amazon.aws.operators.sqs.SqsPublishOperator`

.. exampleinclude:: /../../airflow/providers/amazon/aws/example_dags/example_sqs.py
    :language: python
    :start-after: [START howto_sqs_sensor]
    :end-before: [END howto_sqs_sensor]
