  • Does Java 18 finally have a better alternative to JNI?
    5 projects | dev.to | 11 Apr 2022
    Another popular option is Java Native Runtime (JNR). Though not as widely used or mature as JNA, it's much more modern and has better performance than JNA for most use cases. However, there are some cases where JNA might perform better.

  • Measuring Java 11 Lambda cold starts with SnapStart - Part 4 Using Spring Boot Framework
    4 projects | dev.to | 8 Jan 2023
    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.

    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.

    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
    5 projects | /r/java | 12 Sep 2021
    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)

    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?
    2 projects | /r/java | 17 Apr 2021
    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

    The real comparison would be Quarkus vs Spring Native.
  • Spring Native: Spring Boot but faster
    2 projects | dev.to | 9 Apr 2021
    But in March 2021, something happened in the community of Spring Boot users, and that was the release of the beta program of Spring Native.
