🔹 Kubernetes - Enhancing Kubernetes Event Management with Custom Aggregation

The blog post discusses the challenges of managing and analyzing Kubernetes events as clusters grow. It introduces a custom event aggregation system to help engineering teams better understand cluster behavior and troubleshoot issues more effectively. The main issues with Kubernetes events are high volume, limited retention, lack of correlation, classification, and aggregation. A custom system can group related events, providing quicker insights into patterns such as storage scalability issues. The proposed system uses Go and includes components for watching, processing, and storing events. Key features include event correlation, classification, and storing events with flexible retention policies. Good practices for managing events involve resource efficiency, scalability, and reliability. Advanced features like pattern detection and real-time alerts are also suggested. The conclusion emphasizes improved cluster observability and troubleshooting, with potential future enhancements like machine learning for anomaly detection and integration with observability platforms. 👉 Read more

🔹 Java - Interconnecting Java and Native Code with the FFM API

The blog post titled “Interconnecting Java and Native Code with the FFM API” discusses how the Foreign Function & Memory Access API (FFM API), introduced in Java SE 22, improves the interaction between Java applications and native libraries. It outlines three key enhancements:

  1. The FFM API offers a comprehensive interface to represent off-heap memory as a memory segment.
  2. It provides a robust API to describe and connect with native functions.
  3. It simplifies access to native libraries through a tool called jextract, which automatically generates necessary FFM API components.

The presentation illustrates these FFM principles and demonstrates Java’s integration with native graphics libraries and AI frameworks. 👉 Read more
