Managing visibility timeout in Amazon SQS

This Python example shows you how to specify the time interval during which messages received by a queue are not visible.

The scenario

In this example, Python code is used to manage visibility timeout. The code uses the SDK for Python to manage visibility timeout by using this method of the AWS.SQS client class:

For more information about Amazon SQS visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.

Prerequisite tasks

To set up and run this example, you must first complete these tasks:

  • Create an Amazon SQS queue. For an example of creating an Amazon SQS queue, see Create a queue.
  • Send a message to the queue. For an example of sending a message to a queue, see Send a message to a queue.

Change the visibility timeout

The example below shows how to:


import boto3

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

queue_url = 'SQS_QUEUE_URL'

# Receive message from SQS queue
response = sqs.receive_message(
    QueueUrl=queue_url,
    AttributeNames=[
        'SentTimestamp'
    ],
    MaxNumberOfMessages=1,
    MessageAttributeNames=[
        'All'
    ],
)

message = response['Messages'][0]
receipt_handle = message['ReceiptHandle']

# Change visibility timeout of message from queue
sqs.change_message_visibility(
    QueueUrl=queue_url,
    ReceiptHandle=receipt_handle,
    VisibilityTimeout=20
)
print('Received and changed visibility timeout of message: %s' % message)
