##########################
Using queues in Amazon SQS
##########################

This Python example shows you how to:

* Get a list of all of your message queues

* Obtain the URL for a particular queue

* Create and delete queues

The scenario
============

In this example, Python code is used to work with queues. The code uses the AWS SDK for Python to use 
queues using these methods of the AWS.SQS client class:

* `list_queues <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.list_queues>`_.

* `create_queue <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.create_queue>`_.

* `get_queue_url <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.get_queue_url>`_.

* `delete_queue <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.delete_queue>`_.

For more information about Amazon SQS messages, see 
`How Queues Work <http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-how-it-works.html>`_ 
in the *Amazon Simple Queue Service Developer Guide*.

List your queues
================

The example below shows how to:
 
* List queues using 
  `list_queues <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.list_queues>`_.
  
Example
-------

.. code-block:: python

    import boto3

    # Create SQS client
    sqs = boto3.client('sqs')

    # List SQS queues
    response = sqs.list_queues()

    print(response['QueueUrls'])

.. _aws-boto3-sqs-create-queue:

Create a queue
==============

The example below shows how to:
 
* Create a queue using 
  `create_queue <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.create_queue>`_.
  
Example
-------

.. code-block:: python

    import boto3

    # Create SQS client
    sqs = boto3.client('sqs')

    # Create a SQS queue
    response = sqs.create_queue(
        QueueName='SQS_QUEUE_NAME',
        Attributes={
            'DelaySeconds': '60',
            'MessageRetentionPeriod': '86400'
        }
    )

    print(response['QueueUrl'])

Get the URL for a queue
=======================

The example below shows how to:
 
* Get the URL for a queue using 
  `get_queue_url <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.get_queue_url>`_.
  
Example
-------

.. code-block:: python

    import boto3

    # Create SQS client
    sqs = boto3.client('sqs')

    # Get URL for SQS queue
    response = sqs.get_queue_url(QueueName='SQS_QUEUE_NAME')

    print(response['QueueUrl'])

Delete a queue
==============

The example below shows how to:
 
* Delete a queue using 
  `delete_queue <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.delete_queue>`_.
  
Example
-------

  .. code-block:: python
  
    import boto3

    # Create SQS client
    sqs = boto3.client('sqs')

    # Delete SQS queue
    sqs.delete_queue(QueueUrl='SQS_QUEUE_URL')
