Generally Available: Control Plane Improvements in AKS

We are making improvements to API server resiliency per Kubernetes Enhancement Proposal (KEP) 5116 – Streaming Encoding for LIST Responses. 

 

This enhancement significantly reduces API server memory usage by approximately 10x during large LIST calls to the API server. By lowering memory pressure, it helps improve list call latency and improves the resiliency of the kube-apipserver by reducing the probability of Out-of-Memory (OOM) issues. AKS has backported this upstream feature to make it available to customers using versions below v1.33 with AKS 

• This improvement is now available in AKS Kubernetes v1.31.9 and higher 
• AKS Kubernetes v1.32.6 and higher will be available soon
