Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Reactive Backend Applications with Spring Boot, Kotlin and Coroutines (Part 2)
Kotlin has coroutines that are supported by the language and implemented by a library (the implementation remains platform-dependent): kotlinx.coroutines and a sandbox environment is available here to try it out.
- Kotlinx Coroutines for Kotlin 1.7.x
-
Why no one recommends the use of the standard library's Result class but a custom sealed class approach?
Sure! runCatching catches Throwable right? Well when you cancel a coroutine it throws a CancellationException and this gets used as a signal to stop execution. runCatching stops that signal so the coroutine keeps running. Lemme find you a link real quick https://github.com/Kotlin/kotlinx.coroutines/issues/1814

Is there thread switching when moving from Default dispatcher to IO dispatcher using withContext?
According to the author of kotlinx.coroutines lib, it will try to keep the same thread if possible but not always. After my question, he updated the document of Dispatchers.IO to be like this https://github.com/Kotlin/kotlinx.coroutines/pull/3236/files This dispatcher and its views share threads with the [Default][Dispatchers.Default] dispatcher, so using `withContext(Dispatchers.IO) { ... }` when already running on the [Default][Dispatchers.Default] dispatcher typically does not lead to an actual switching to another thread. In such scenarios, the underlying implementation attempts to keep the execution on the same thread on a best-effort basis.
I think it is a great question and you can ask it on github
This is the issue I posted in GitHub https://github.com/Kotlin/kotlinx.coroutines/issues/3234 Thank you for the suggestion

Am I on the right track?
DI: Dependency injection: Check out Dagger Hilt, Koin or Kodine. Architecture: Android tends to be MVVM but, MVP, MVI and some others exist. Async calls: For kotlin, coroutines. Rxjava can be used with kotlin or java. I'm not actually sure how java devs do asyn calls these days.

Java Virtual Threads Preview
Interestingly, Kotlin Coroutines have been available and in production for a LONG time now.
https://github.com/Kotlin/kotlinx.coroutines
In fact, Kotlin Coroutines are an brilliant on the android platform. We are talking severely memory and CPU constrained architectures here.
That said, Kotlin Coroutines are popularly used in production on server side - https://vertx.io/docs/vertx-lang-kotlin-coroutines/kotlin/
So here's the thing - I would doubt anyone would switch to Java Virtual Threads anytime soon.

Need Help Testing Callback Style Code with Coroutines
Anyways, it seems like it's a common enough issue that it is getting the attention of the kotlin team. I have high hopes for this PR that looks like it might be close to merging, and has activity within the last couple of days.

Measuring Java 11 Lambda cold starts with SnapStart - Part 4 Using Spring Boot Framework
It was probably not a very good idea to write Lambda using Java programming language and Spring Boot Framework. Despite the well-spread usage and knowledge of this framework, the fact that Spring (Boot) heavily uses reflection and takes time to start the embedded Web Application Server led to very big cold starts which we'll explore in the next section. But now with SnapStart on AWS and GraalVM Native Image Support we have two more options how to optimize those cold starts. So let's explore how to write Lambda function using the Spring Boot. The code of this sample application (the same as for the first 3 parts but rewritten to use Spring Boot) can be found here. It provides AWS API Gateway and 2 Lambda functions: "CreateProduct" and "GetProductById". The products are stored in the Amazon DynamoDB. We'll use AWS Serverless Application Model (AWS SAM) for the infrastructure as a code.

Introducing Spring Native for JHipster: Serverless Full-Stack Made Easy
During this experience, I was surprised to find that Spring Native doesn't support caching yet. I believe this support will be added by the community soon. In the meantime, if you're looking to start/stop your infra as fast as possible, you probably don't care about caching. Caching is made for long-lived, JVM-strong, JVM-loving apps.

Annotation-free Spring
As I just found out thanks to a comment from another Redditor, spring-aot will be getting some functional configuration compile time generation support in Spring Native's next release
But I just took a peek at Spring Native roadmap for 0.11 and they will be adding some of the spring-fu and spring-init-inspired functional configuration to spring-aot project (which, like I mentioned in another comment, already has compile-time generation support for various dynamic proxies that you mentioned)

Kotlin Team AMA #3: Ask Us Anything
Our next steps are : provide great Kotlin/JVM/Native (Native with Kotlin JVM via GraalVM native images) support via https://github.com/spring-projects-experimental/spring-native/, empowering multiplatform development (with Kotlin/JS frontend for example), translating Spring Boot documentation to Kotlin (via a contribution from Kotlin team), make sure that some APIs like WebTestClient currently broken with Kotlin due to some type inference bugs with recursive generic types become usable.

Is it right to use Spring & Spring boot?
I doubt micronaut has better runtime performance. You're probably talking about startup time and this point is moot with either https://github.com/dsyer/spring-boot-auto-reflect Or https://spring.io/blog/2021/03/11/announcing-spring-native-beta

Why I use Quarkus rather than Spring-Boot for my CNA apps
The real comparison would be Quarkus vs Spring Native.
