Kubernetes v1.36: Server-Side Sharded List and Watch

Kubernetes v1.36 introduces server-side sharded list and watch as an alpha feature to reduce the volume of data flowing from the API server. This feature filters events at the source, allowing each controller replica to receive only the slice of the resource collection it owns. This reduces CPU, memory, and network costs. To use this feature, clients specify a hash range using the shardRange() function and the API server computes a deterministic hash of the specified field to return only matching events.
