AWS SnapStart - Part 15 Measuring cold and warm starts with Java 21 using different synchronous HTTP clients
In this article we'll now add another dimension to our measurements : the choice of HTTP Client implementation. This is also interesting, because starting from AWS SDK for Java version 2.22 AWS added support for their own implementation of the synchronous CRT HTTP Client. The asynchronous CRT HTTP client has been generally available since February 2023. In this article we'll explore synchronous HTTP clients first and leave asynchronous ones for the next article.

Creating RSS feeds for language/module specific AWS SDK updates
The updates could be parsed from the github repo's CHANGELOG files (ex: javascript, java, python). I'm picturing an RSS feed generated for a specific language and module (ex: python s3, javascript s3, java sqs)

Using Cognito to provide auth to a Java desktop application - advice requested
Meanwhile the [SDK doesn't provide samples or an API for USER_SRP_AUTH AuthFlow](https://github.com/aws/aws-sdk-java-v2/issues/2851). (I don't think that's the right choice, anyway, because if I'm right I'd have to register my user in my new app, and I don't want to do that).

Latest java vs Kotlin?
Bonus: AWS SDK for Java v2 - this one I'm not sure of their reasons, but this request to add nullability annotations was filed 4.5 years ago, and there has been virtually no movement or feedback on it, so I can only speculate about their reasons for not fixing this.

Need help with the weird behavior of the AWS pagination token
If you think its a genuine bug in the API or the client somehow I think opening an issue in the github repo for the sdk might be a good place to start https://github.com/aws/aws-sdk-java-v2/issues .

Improving Python S3 Client Performance with Rust
Should be possible to just issue a GetObject with a range for the initial request skipping a head request. See here for caveats about how the Content Range data is returned in the response header: https://github.com/aws/aws-sdk-java-v2/issues/1209

I have used hikari and exposed to do this in the past with postgres, although other dialects are supported.

A Tale of Two Connection Pools
I found one suggestion from the author of HikariCP on how to address this, which I implemented and it worked. However, there are additional classes involved, and it feels a little clunky and hard to follow.

Spring boot change password runtime
Not really, you can change some things in spring boot but doing so will typically trigger a refresh which is less reliable than restarting but still causes a large performance hit. You could probably do it with hikari if you really needed to but it's inadvisable to build your application around this mechanic.

Should I use diesel ORM if performance is the most important thing?
Whatever you choose, presuming your app is database heavy, I highly recommend spending time on DB schema design to make all queries as short as possible, avoid relying on transactions, and keep your connection pool tiny. For reference: https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing

Art of README
You reminded me of the HikariCP library and it’s documentation: Clear and simple with references to other libraries trying to accomplish the same thing. It is not in the closure space though.
