http4k-connect 3.40.4.0 released with OpenAI API support
http4k-connect is a set of lightweight (zero-reflection) API libraries for connecting to popular third-party cloud services using http4k clients, along with Fake implementations for usage during local testing. It is based around the Connect pattern, which allows you to express client-side adapters in modular and composable way.

How is the market for Kotlin developers where you live?
Great stack! Just out of interest , any reason you don't use Http4k connect for your AWS needs?

Experienced Java/Kotlin developers: what libraries do you use in your day to day work?
TBH, the official SDK dynamo client library isn't great for either. If you're looking for something lightweight, you could try http4k-connect - the dynamo client API is much nicer, does type-safety by plugging into the http4k lens system, and is zero reflection (using Moshi and generated adapters), which means you can simply cross compile to GraalVM. We're using it for native Kotlin Lambdas using the custom http4k Lambda runtime and it's 🚀🚀🚀. You can also use it backed by the OkHttp client wrapper if you want.

Writing to db
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.
