the cluster to achieve better scalability. The concept of CiliumEndpointSlice is described in: EndpointSlice CRD When enabled, Cilium operator watches CEP objects and group/batch slim versions of them into DELETE event. This should greatly reduce the probability of connection disruption in most cases. EndpointSlice CRD When managing pods in Kubernetes, Cilium will create a Custom Resource Definition (CRD) of integration in detail: Introduction Concepts Requirements Configuration Network Policy Endpoint CRD EndpointSlice CRD Kubernetes Compatibility Cilium CRD schema validation Troubleshooting Introduction What
