If you dont use an AWS SDK to access Amazon SQS, or if you configure an AWS SDK to have a shorter wait. If 20 seconds is too long for your application, set a shorter ReceiveMessage wait time (1 second minimum). Serverless Error -Īn error occurred: LambdaEvConf - 1 validation error detected: Value '3' at 'maximumRetryAttempts' failed to satisfy constraint: Member must have value less than or equal to 2 (Service: AWSLambdaInternal Status Code: 400 Error Code: ValidationException īut when I look at the console, I can increase this number all the way to 1000: For optimal message processing, use the following strategies: In most cases, you can set the ReceiveMessage wait time to 20 seconds. I’d like to increase that, but when I try to deploy I get this error: With this, the function tries 2 times before the message gets to the DLQ. MessageRetentionPeriod: 604800 # 7 days in seconds Im using aws messaging and not JMS, so my annotation would be SQSListener for my listener method. Here’s the relevant serverless.yml portion: resources: How do I add a DLQ configuration to my SQS configuration Im not sure how to integrate a DLQ with my existing queue. I’d like to have it re-try a few times before the message gets to the DLQ. Update the AWS SDK to improve CPU and memory usage and reduce latency when using Amazon SQS.I have a service that uses an SQS fifo queue as trigger for a lambda function. More recently, Amazon SQS added new APIs to manage dead-letter queue (DLQ) redrive programmatically. Just a few months back, we introduced server-side encryption with Amazon SQS-managed encryption keys (SSE-SQS) by default for newly created queues, increased the default quota for high throughput mode for FIFO queues, and announced support for attribute-based access control (ABAC) using queue tags. If you’re interested in more details on how AWS protocols work, you can have a look at Smithy, the language we use at AWS for defining services and SDKs.Īfter almost 17 years of being generally available, we’re improving and innovating around our oldest service. For more information, see Amazon SQS pricing. There is no change in pricing when using the AWS JSON protocol. To get the benefits of this optimization, you just need to update the AWS SDK to the latest version available. All generally available AWS SDKs now support AWS JSON for SQS APIs. These numbers depend on the actual implementation and can differ from what you’ll see for your own applications.Īmazon SQS support for the new JSON protocol is available today in all AWS Regions where SQS is offered. Based on AWS performance tests for a 5KB message payload, JSON protocol for Amazon SQS reduces end-to-end message processing latency by up to 23 percent and reduces application client side CPU and memory usage. We expect similar results from the other AWS SDKs. While building this new capability, the SQS team was careful so that no code changes are needed to use the new JSON-based wire protocol.įor example, we ran a benchmark using the AWS SDK for Java to compare the old and new wire protocols. This is the nicest part of this launch! To benefit from the AWS JSON protocol, you just need to update the AWS SDK to the latest version. Using the New JSON-Based Protocol with Amazon SQS For more information about Amazon SQS dead letter queues, see Using Amazon SQS Dead Letter Queues in the Amazon Simple Queue Service Developer Guide. The content length of the same SendMessage response using the new AWS JSON protocol is less than 1/3 of the previous size. The code uses the SDK for Python to use dead letter queues using this method of the AWS.SQS client class: setqueueattributes. For example, for a request that sends a simple “hello world” message, the response body size using the old AWS Query protocol is about 400 bytes. The AWS JSON protocol avoids many of the shortcomings of AWS Query protocol.ĪWS JSON is more efficient than the previous XML-based protocol and can reduce both latency and client-side CPU usage when sending and receiving SQS messages. The default policy is NOREDRIVE because it is the. Today, I am happy to announce that Amazon SQS now supports a JSON-based wire protocol for all APIs. The deletion policy can be set individually on every listener method using the SqsListener annotation. In fact, Amazon SQS has been generally available since July 2006 and, under the hood, has always used the same wire protocol based on XML that we call AWS Query protocol. It was one of the first AWS services I used and as a Solutions Architect, I helped many customers take advantage of asynchronous communications using message queues. With Amazon SQS, you can send and receive messages between software components at any scale.
