Nov 5, 2013 · Based on your description of the problem, my conclusion was that you were inadvertently causing this with the console or you have a consumer listening to the queue that you aren't aware of or that your code that interfaces to SQS is actually getting occasional messages and telling your app nothing was received due to a bug, because the behavior you describe …

Anyhow, typically a Lambda function would be invoked with a batch of messages e.g. 100 or more per invocation. There’s no API Gateway in that scenario. The AWS Lambda service polls the SQS queue and invokes the Lambda function as needed, and potentially invokes many instances of the Lambda function, each processing a batch.

The service doesn't call AWS, but instead returns a set response that you can modify to suit your needs (the XML response files are in the Mock directory). The mock service makes it easy for you to test how your application handles different responses. For SQS, it appears the Perl and PHP SDKs have mock mode.

May 18, 2015 · @ÖzerS. currently the fan-out pattern described above using SNS & SQS supports only SQS standard queues. As of today, SQS FIFO queues are not supported. I haven't yet found out if there is any intention from AWS to support this in future. –

Dec 3, 2012 · AWS SNS is a publisher subscriber network, where subscribers can subscribe to topics and will receive messages whenever a publisher publishes to that topic. AWS SQS is a queue service, which stores messages in a queue. SQS cannot deliver any messages, where an external service (lambda, EC2, etc.) is needed to poll SQS and grab messages from SQS.

Aug 20, 2014 · On AWS CLI the command I used is: aws sqs receive-message --queue-url <url of DLQ> --max-number-of-messages 10. Since the max messages you can read caps at 10, I suggest running the command in a loop like this: for i in {1..1000}; do <CMD>; done

Nov 22, 2018 · If you must use SQS, then you will need to have a lambda function to act as a proxy. You will need to set up the queue as a lambda trigger , and you will need to write a lambda that can parse the SQS message and make the appropriate call to the Step Functions StartExecution API .

Mar 31, 2022 · SQS never "pushes" messages anywhere, it is a "pull" service. With that in mind, when moving to ECS you would need to change your code so that it polls SQS for messages to process. In general the way to configure this is to have a docker image that, when spawned as a container simply polls the SQS queue forever, processing any messages it receives.

Aug 17, 2014 · Just a simple question, but I can't seen to find the answer. Is it possible to use the API, to get the queue size (the number of messages/jobs waiting to be processed) of an AWS SQS queue? Prefe...

Feb 25, 2017 · When working with SQS, best practice is to ensure your SQS message processing is idempotent. Meaning that processing the same message multiple times will yield the same results. What this means exactly depends on your business logic. You could track the SQS message IDs to determine if they have been processed already.
