Kafka 4.0 AOT Cache Boosts Startup Time by 59%
2025-03-28
This article demonstrates how to leverage Java's Ahead-of-Time (AOT) compilation to significantly improve the startup time of Apache Kafka 4.0. By creating an AOT cache file, the author successfully reduced Kafka's startup time from 690 milliseconds to 285 milliseconds, a remarkable 59% improvement. The process involved overcoming a JMX conflict, ultimately leading to the successful creation and application of the AOT cache, resulting in substantial performance gains.
