🔹 Kubernetes - Kubernetes v1.34: Snapshottable API server cache

The blog post discusses the enhancements introduced in Kubernetes v1.34, focusing on the “snapshottable API server cache” feature, which has progressed to Beta. This feature is part of a broader effort to improve API server stability and performance by mitigating memory usage and load on the etcd datastore. Key improvements in previous releases included consistent reads from the cache (Beta in v1.31) and streaming large responses (Beta in v1.33). The new feature allows for efficient, point-in-time snapshots of the cache, enabling almost all read requests to be served from memory, reducing memory pressure, and stabilizing the control plane. The “SnapshottableCache” feature gate is enabled by default in Kubernetes v1.34, requiring no user action to leverage these improvements. Acknowledgments are given to various contributors from different organizations for their roles in implementing these features. 👉 Read more

🔹 Spring Boot - Access API Moves to Spring Security Access

The blog post discusses the transition of Spring Security’s authorization API over the past five years, leading to new features like Authorized POJOs, value masking, and planned Multi-Factor Authentication in Spring Security 7. The transition deprecated most of the Access API components, such as AccessDecisionManager and FilterSecurityInterceptor, along with @EnableGlobalMethodSecurity. To aid organizations in migrating, Spring Security 7.0.0-M3 introduces an optional module, spring-security-access, containing the deprecated components. This module is necessary only for applications still using the old Access API components. For those already using AuthorizationManager, no changes are needed. The post provides migration hints to help with the transition. 👉 Read more
