Summary
Kubernetes v1.37 moves etcd RangeStream to beta, and with etcd v3.7 it lowers the memory the API server and etcd need for large collection reads while making peak usage more predictable.
Key facts
- RangeStream reaches beta in Kubernetes v1.37.
- It is paired with etcd v3.7.
- It cuts memory needed to read a large collection.
- Peak memory usage becomes more predictable.
Why it matters
Operators running large clusters can expect lower and more predictable memory use when the API server and etcd read large collections, which may ease capacity planning for list and watch traffic.
