New for Amazon SQS – Replace the AWS SDK to scale back latency

Voiced by Polly

With Amazon SQS, you possibly can ship and obtain messages between software program parts at any scale. It was one of many first AWS providers I used and as a Options Architect, I helped many purchasers benefit from asynchronous communications utilizing message queues. In actual fact, Amazon SQS has been typically accessible since July 2006 and, below the hood, has all the time used the identical wire protocol based mostly on XML that we name AWS Query protocol.

At present, I’m completely happy to announce that Amazon SQS now helps a JSON-based wire protocol for all APIs. The AWS JSON protocol avoids most of the shortcomings of AWS Question protocol.

AWS JSON is extra environment friendly than the earlier XML-based protocol and may scale back each latency and client-side CPU utilization when sending and receiving SQS messages. For instance, for a request that sends a easy “whats up world” message, the response physique measurement utilizing the outdated AWS Question protocol is about 400 bytes. The content material size of the identical SendMessage response utilizing the brand new AWS JSON protocol is lower than 1/3 of the earlier measurement.

Utilizing the New JSON-Based mostly Protocol with Amazon SQS
That is the nicest a part of this launch! To profit from the AWS JSON protocol, you simply have to replace the AWS SDK to the most recent model. Whereas constructing this new functionality, the SQS group was cautious in order that no code adjustments are wanted to make use of the brand new JSON-based wire protocol.

For instance, we ran a benchmark utilizing the AWS SDK for Java to check the outdated and new wire protocols. We count on related outcomes from the opposite AWS SDKs. Based mostly on AWS efficiency assessments for a 5KB message payload, JSON protocol for Amazon SQS reduces end-to-end message processing latency by as much as 23 p.c and reduces software shopper facet CPU and reminiscence utilization. These numbers rely upon the precise implementation and may differ from what you’ll see in your personal functions.

Availability and Pricing
Amazon SQS help for the brand new JSON protocol is offered in the present day in all AWS Areas the place SQS is obtainable. All typically accessible AWS SDKs now help AWS JSON for SQS APIs. To get the advantages of this optimization, you simply have to replace the AWS SDK to the most recent model accessible.

There is no such thing as a change in pricing when utilizing the AWS JSON protocol. For extra data, see Amazon SQS pricing.

If you happen to’re focused on extra particulars on how AWS protocols work, you possibly can take a look at Smithy, the language we use at AWS for outlining providers and SDKs.

After nearly 17 years of being typically accessible, we’re bettering and innovating round our oldest service. Just some months again, we launched server-side encryption with Amazon SQS-managed encryption keys (SSE-SQS) by default for newly created queues, elevated the default quota for top throughput mode for FIFO queues, and introduced help for attribute-based entry management (ABAC) utilizing queue tags. Extra lately, Amazon SQS added new APIs to handle dead-letter queue (DLQ) redrive programmatically. At AWS, it’s all the time day 1!

Replace the AWS SDK to enhance CPU and reminiscence utilization and scale back latency when utilizing Amazon SQS.
