🔹 Kubernetes - Kubernetes v1.33: Streaming List responses

The blog post discusses a new feature in Kubernetes v1.33 that introduces streaming encoding for List responses, which addresses the challenge of unnecessary memory consumption when handling large datasets in Kubernetes clusters. Previously, large List requests could significantly impact cluster stability due to high memory usage, potentially leading to Out-of-Memory (OOM) situations. The new streaming encoding mechanism processes and transmits each item in a List response individually, allowing memory to be freed progressively. This approach reduces the memory footprint of the API server, improves scalability, increases stability, and optimizes resource utilization. Benchmark results show a 20x improvement in memory usage, reducing it from 70-80GB to 3GB during large List operations. The change is backward compatible, requiring no modifications on the client side. 👉 Read more
