GitOps for 15,000+ clusters hits memory wall at about 20k cached objects in hub controllers. Testing used vCluster and ArgoCD; tuning helps but architecture matters most at extreme scale.
Key points
Memory wall: hub controllers hit memory limits around 20k cached objects.
Scale exposure: running GitOps across 15,000+ clusters exposes raw controller limits fast.
