• Policies are important in protecting against disruption and cluster maintenance in a NoSQL database deployment
• Without policies, evicting or draining nodes during maintenance can result in lost parts and production outrage
• Creating policies per replica ring can help protect against disruptions
• Distributed policies can provide protection for complex NoSQL database deployments
• Multi-cluster mode requires separate service accounts, service, and RBAC to extract tokens to allow controllers to talk to other clusters
• Building a fully compatible controller to the built-in type is a formidable challenge
• Democratizing extensibility for building types is desirable
