Apache Kafka 3.8 版本发布，带来多项新特性
Apache Kafka 是一个分布式流处理平台，广泛应用于消息传递和事件驱动型系统中。近日，Kafka 3.8 版本正式发布，带来了多项新特性，旨在进一步提升系统的性能和用户体验。
新版本中最引人注目的是对 Broker 启动时间的优化。通过引入基于 GraalVM 的 Native Docker Image，Broker 的启动时间被显著缩短至 140ms 以内，相较于之前的 3s 有了极大的提升。这一改进将大大提高大规模 Broker 测试的效率。
此外，Kafka 3.8 版本还引入了官方 Docker Image，提高了镜像的安全性和透明度。同时，新版本对消费者重平衡协议进行了重大更新，通过将复杂性转移到组协调者，解决了过去依赖于客户端日志和全局同步屏障的问题。
在日志方面，Kafka 3.8 版本弃用了 log4j-appender，并升级了所有相关的模块到 log4j2，以彻底移除 log4j 工件，解决了日志输出不正确的问题。
在压缩方面，3.8 版本提供了压缩级别的配置，允许用户根据需要调整压缩率和性能之间的平衡。
最后，新版本还对文件和目录配置提供者进行了安全改进，以限制访问的文件和目录，增强了系统的安全性。
总体而言，Apache Kafka 3.8 版本的新特性旨在为用户提供更加高效、安全、可靠的服务，满足云原生时代的需求。随着这些新特性的加入，Kafka 将继续在消息传递领域发挥重要作用。

Apache Kafka 3.8 Release Brings New Features
Apache Kafka is a distributed streaming platform widely used in message and event-driven systems. Recently, the Kafka 3.8 version has been officially released, bringing several new features aimed at further improving system performance and user experience.
Among the new features, the optimization of Broker startup time is particularly noteworthy. By introducing a Native Docker Image based on GraalVM, the startup time for Brokers has been significantly reduced to less than 140ms, a significant improvement over the previous 3 seconds. This enhancement will greatly enhance the efficiency of large-scale Broker testing.
Additionally, the Kafka 3.8 version introduces an official Docker Image, which improves the security and transparency of the image. Furthermore, the new version has undergone a major update to the consumer rebalancing protocol, moving complexity to the group coordinator, solving issues that relied on client logs and global synchronization barriers in the past.
On the log front, the Kafka 3.8 version has deprecated the log4j-appender and upgraded all related modules to log4j2, completely removing log4j artifacts and addressing issues with incorrect log output.
In terms of compression, the 3.8 version provides configurable compression levels, allowing users to adjust the balance between compression rate and performance as needed.
Lastly, the new version has made security improvements to the file and directory provider, limiting access to files and directories and enhancing system security.
Overall, the new features of the Apache Kafka 3.8 version are designed to provide users with more efficient, secure, and reliable services, meeting the needs of the cloud-native era. With these new features, Kafka will continue to play a significant role in the messaging domain.
