Time Box: 1 sprint

Adaptable topology is a cluster-topology mode that adjusts cluster control-plane and infrastructure behavior based on the current number of control-plane and worker nodes. The goal of this spike is to update the enhancement proposal with the answers to the following questions.

Research Questions

• Which core operators have unique behavior based on controlPlaneTopology and infrastructureTopology values today?
• Is adding new infrastructureTopology values similar to adding controlPlaneTopology values, or are there special considerations?

Involved Teams

• Operator Teams (console, ingress, TBD)
• Control Plane (cluster-etcd-operator)

Acceptance Criteria

• Complete audit of core operators with topology-specific behavior
• Document differences between controlPlaneTopology and infrastructureTopology changes
• Identify special considerations for infrastructureTopology values
• Update enhancement proposal with operator audit results and recommendations

Additional Context

• Enhancement Proposal: https://github.com/openshift/enhancements/pull/1905
• Initial topology audit shows 30 in-payload operators (24 reference topology APIs)
• Related to Core Operator Changes section of enhancement
• Should validate findings in Initial Topology Audit table
