🔹 Kubernetes - Kubernetes v1.33: Streaming List responses

The blog post discusses the release of Kubernetes v1.33, which introduces streaming encoding for List responses, addressing the challenge of unnecessary memory consumption when handling large-scale List requests in Kubernetes clusters. Previously, the entire response was serialized into one memory block, causing high memory usage and potential stability issues. The new streaming encoder processes and transmits each item individually, allowing for progressive memory freeing and reducing the memory footprint of the API server. This change enhances cluster stability, scalability, and resource utilization. Benchmark results show a significant reduction in memory usage, improving from 70-80GB to 3GB when handling large requests. The streaming encoder is fully backward compatible, requiring no changes from the client side. 👉 Read more
