KEP of the Week

KEP-3157: Allow informers for getting a stream of data instead of chunking

This KEP addresses the kube-apiserver’s vulnerability to excessive memory consumption caused by LIST requests in large clusters, which can lead to server crashes, node pressure, and workload disruption. To solve this, it proposes reducing temporary memory usage from an exponential scale to a manageable constant, leveraging the watch cache to reduce etcd load, ensuring consistent and fresh LIST responses, and maintaining backward compatibility—all while protecting the server and its node from OOM scenarios

This KEP is tracked for beta release in the ongoing v1.32 cycle.

Other Merges

Validate DRA Node Selector Labels even on upgraded objects; while this is a backwards-incompatible change, it’s not expected to break anything

Version Updates

golang to 1.23.3 in 1.32, and to 1.22.9 in older releases
