版本，了解一个库中刚发现的漏洞对整个企业的影响，以及对从同一模板创建的多个服务应用更新时。在这一领域，Sourcegraph 仍然是一个很受欢迎的工具。OpenRewrite 是另一个我们想提及的工具。我们的团队已经在 Java 中使用它解决特定的问题，比如更新用入门套件创建的服务。目前它仍在持续拓宽覆盖的语言和使用案例。我们喜欢它附带的变革方案，这些方案描述了需要进行的更改，例如用于跨版本迁移常用框架。重构引擎、捆绑方 Kotlin with Spring ## 试验 五年前，我们将 Kotlin 移至了采纳阶段，如今我们的许多团队报告称，Kotlin 不仅成为了他们在 JVM 语言上的默认选择，而且已经几乎完全取代了 Java，成为他们编写软件的主要语言。与此同时，microservice envy 似乎正在减弱，我们注意到人们开始使用诸如 Spring Modulith 等框架，探索具有更大可部署单元的架构。我们已经知道有许多出色的 Netflix DGS，体验很好。Netflix DGS 基于 graphql-java 开发，并提供了许多 Spring Boot 编程模型的特性与抽象。因此使得开发 GraphQL 端点，以及与 Spring Security 等 Spring 特性集成就变得很容易。虽然 DGS 是用 Kotlin 编写的，但在 Java 上它也工作的很好。 ### 93.

rather have a fast cache, or a slower cache that is larger. Many popular application runtimes (e.g. Java jre) have similar NUMA related issues. ## How can NUMA issues be avoided? Application can be modified effects. (e.g. interleaving get predictable albeit reduced performance) - A cgroup aware version (e.g. Java jre v10) can be deployed - This is often not available – many were developed in a pre-container era
