The Exposed framework offers a unique solution to common challenges encountered when working with the JDBC API, setting it apart from frameworks like Hibernate. Its lightweight approach, which eschews the need for extensive mapping and provides type-safe access, leverages the expressiveness of Kotlin. This results in a DSL-like solution that enhances code readability and comprehension.

@stahlbrandt Nothing helped (republish, recreating content, re-adding image, etc ...). But another blog with the same content is fine https://www.atbash.be/2023/09/04/temp/.
But can't give that the same URL as the faulty one.

@stahlbrandt Seems to be a problem with this blog entry only. No idea why, I tried a lot of things. I removed the cookie consent plugin like 6 months ago and still there.

@stahlbrandt Weird, looks like some Wordpress Issue. Screenshot is from the mastodon feed, article should be more on top.
Mobile Preview in Wordpress is ok.

This blog contains some of the performance issues I encountered in my Java career with ORM tools like Hibernate: https://www.atbash.be/2023/09/03/why-orm-and-data-frameworks-are-not-your-best-option/

It contains a few best practices if you make use of an ORM tool or a Data framework to keep your data retrieval performant in production.

But maybe you should not use them at all and just use a lightweight tool that abstracts away the JDBC API and takes care of the mapping.

In my comparison about runtime startup I published two months ago ("Time is code, my friend, https://www.atbash.be/2023/03/12/time-is-code-my-friend/), Kotlin and Ktor performed very well.

In this first blog, I quickly go over a few aspects why you might consider Kotlin and Ktor for your next backend application. For the Jakarta EE users, it shows some of the functionality of JAX-RS, JSON-P and JSON-B.

Here is the link to the blog: https://www.atbash.be/2023/05/02/why-dont-you-create-your-next-backed-end-application-with-kotlin-and-ktor/

When Should we Move to Microservices?

How to avoid the small monolith anti-pattern?

At what scale do Microservices make sense?

Avoid a solution worse than the problem and understand the tradeoffs.

With the new changes to #docker Hub around Free Teams, It seems #testcontainers will now loose its "Sponsored OSS" badge and our users will start to suffer from pull-rate limits.

What Docker Hub alternatives to OSS projects currently recommend? We had quite bad experiences with quay.io in the past, created a lot of flakiness. GHCR maybe?

Start-up time comparison of 10 #Java and #Kotlin frameworks by an independent expert, @rdebusscher: https://www.atbash.be/2023/03/12/time-is-code-my-friend/
From start to serving the first request, some frameworks can be as fast as 600ms.

@pgmjsd @preslavrachev Should popularity be a real factor? Is it important that the framework has a huge marketing machine behind it that fuels hype or presents half of the truth?

As for your last question about cost, it should indeed be the main driving factor, but it is only minorly affected by the framework used. For example, memory required for your application data out factors the runtime many times.

@preslavrachev As mentioned, the comparison is to indicate that fast startup time comes with the cost of reduced functionality. A full-blown application on Payara Micro, with clustering and cloud capabilities, still starts in about 10 sec.
My HttpServer implementation that starts in 158 ms can just reply with a JSON.
In reality, you have the entire picture from designing, developing, maintaining, and running your app which can be completely different.

For those who still believe that fast startup times are crucial for the success of their Java applications, I compared 10 Java and Kotlin frameworks.

Besides the obvious conclusion that having more functionality in the framework and the application, the slower the start-up time is, you get also some interesting differences between #Java, #SpringBoot, #Quarkus, #ktor, and others.

"Consensus: we should always start with a #monolith. It’s easier to build, and we can break it down later if we choose to go with microservices. But why should we?" @debugagent discusses all the details, plus video.
