Hello SIG Autoscaling,
We've prepared a proposal on coordinated/ratio-based scaling for interdependent services (e.g., chained microservices, LLM pipelines).
The document outlines the architectural paths for this functionality:
In-Tree Modification: Extending the core HPA API to manage multiple proportional targets.
Custom Resource: Creating an orchestrating Custom Resource Definition (e.g., HPAGroup) built atop existing HPAs.
We seek initial feedback on whether this is better pursued immediately as a KEP proposal for an in-tree solution, or if we should start an incubation subproject (CRD) within SIG Autoscaling to refine the concept first.
Thank you,
