Reactive Backend Applications with Spring Boot, Kotlin and Coroutines (Part 1)
Now that we have an application, let's turn it into a reactive application. For this, we will replace Spring Web dependency with Spring WebFlux, Spring Data JPA with Spring Data R2DBC. We will also add R2DBC dependency for our H2 database. R2DBC works with a reactive driver so it will integrate nicely with the rest of our application to allow us database access in a non-blocking way.

I need to create an API, but I don't know what framework to use. What would you choose, of you were me, and scalability is a quite important factor?
However, if you really expect a lot of users (especially concurrent ones) to use your API, you should delve into the world of reactive programming. Use tools like RxJS (JS/TS) or Project Reactor (Java) in such a case, preferably in combination with a broker like Kafka or RabbitMQ. R2DBC is also great for a data store. Then of course if you want to go one step further, there also exists the less popular but very interesting Actor model which Akka easily has ported into Java.

Walmart is migrating the remaining F# code into Java
- Usually manually wired and configured vs the spring boot "starter" pattern of having libraries that automatically do some of the manual setup work for you: https://github.com/spring-projects/spring-boot/blob/main/spr...
I wish more client library sets had the feature-matrix that the pulsar one does, because in practice most end up being the same: Java supports everything because it's either built in the same codebase or is the most used client and gets the most support, while the dotnet client codebase has many feature-requests or performance improvement issues, often leading to a "third-party client" being created.

Spring Boot 3 And Java 17 Migration Guide
If you’re currently running with an earlier version of Spring Boot, I recommend that you upgrade to Spring Boot 2.7 before migrating to Spring Boot 3.0. It minimizes compatibility issues as much as possible.

Netflix Uses Java
It's weird that some people including you directly attack my competence. As a power user you should have plenty of experience getting something to work that is not properly document, does not work how the documentation promised it to, or has weird problems on top of it. Look at idiotic things like this:
https://github.com/spring-projects/spring-boot/issues/33044
Take any similar issue and you'll see a bunch of people who try to find a solution for them because they just aren't repeatable at all. The underlying issue is the auto configuration doing things you can't follow quite properly. It's like it wasn't mean to be understood. Issues like the one I linked above also show me that the spring dev crowd also doesn't understand the ecosystem anymore. The problem is complexity and automagic.
