General Availability of the AWS SDK for Rust

Hello! Me and some other folks who work on the Rust SDK will be around today answering questions in the comments.

I attended a re:Invent session yesterday on using Rust as a Lambda runtime. The potential performance improvements, especially with limited memory, was quite compelling. I’m looking forward to trying this SDK out with Rust Lambdas.

I realize this is a "how long is a piece of string" question, but I'm wondering what cost benefits you might realistically see from moving lambdas from Python to a faster language like Rust? You pay (partly) for execution time so I guess you should see some savings, but I'm wondering how that works out in practice. Worth it?

I'm a Rust beginner, so please excuse any naivete herein: Does this SDK _necessarily_ require an async runtime or is it possible to use it in a traditional sync application using whatever extra facilities (e.g. block_on) which would be required to "normalize" it?

Hi! Congratulations on GA! Been waiting for this.<p>I just heard about AWS CRT at the AWS ReInvent Innovation talk on Storage.<p>1. Does the Rust SDK use CRT under the hood? I use the Rust SDK to access S3 and wonder if there are any automatic performance gains?<p>2. I couldn&#x27;t find good material on how AWS CRT works and how it is integrated with the Java or Python S3 connectors. I would appreciate a more technical explanation. Do you have any links that explains this in more depth?

Huge. I&#x27;ve told people before that the SDK was basically stable, but the fact that it wasn&#x27;t 1.0 was still concerning for them.

I&#x27;ve been testing this for a while!<p>One thing I sorely missed was workers for consuming SQS messages. Ended up having an intern adapt a worker for the old community AWS SDK (rusoto) into this: <a href="https:&#x2F;&#x2F;github.com&#x2F;Landeed&#x2F;sqs_worker">https:&#x2F;&#x2F;github.com&#x2F;Landeed&#x2F;sqs_worker</a><p>Also on my dream list of features: gRPC support for Lambda.

Sounds like that must have been an absolute bitch to build. I cannot imagine re-implementing 300 existing API’s for Rust from scratch…<p>On the plus side, I guess the work lends itself well to parallelization.

What are some valid reasons why people wouldn&#x27;t now use these rust libraries and extend them to their preferred language? Maintaining clients is tedious work and prone to abandonment.
