Limitation of more than 64 backend pods for a Single Service on Windows nodes needs to be removed from documentation #135518
Description
What happened?
https://kubernetes.io/docs/concepts/services-networking/windows-networking/#limitations states the following as one of the things not supported:
More than 64 backend pods (or unique destination addresses) for a single Service
The original trigger for this documentation is #98680 apparently, which led to microsoft/Windows-Containers#93. Comments in the latter issue say that the issue has been fixed with the limit increased to 1024. By now (3 years later), I believe the limitation has been fixed in Windows Server in both 2019 and 2022.
What did you expect to happen?
If the above is true, then can the limitation be removed from the documentation?
How can we reproduce it (as minimally and precisely as possible)?
Documentation needs update, no repro required.
Anything else we need to know?
FWIW, in my test with an Azure Kubernetes Service (AKS) cluster and a Windows Server 2022 node pool, I created a StatefulSet with 70 Windows pods behind a ClusterIP Service - didn't observe any issue on any of the Windows nodes.
