- DMaaP communication over multiple namespaces.
- Policy DB communication over multiple namespaces. Mainly the security credentials generated randomly during DB pod creation.
- Planning of what policy components needs to be centralized vs de-centralized and moved to tenant namespaces.
- How DCAE/OOF or any other client decides which PDP engine to call for making decision. This is valid for scenarios where clients are making a REST (or any) call directly to PDP engine. Currently supported by Xacml-PDP.
- Are there any impacts to CLAMP or any other clients who want to create/deploy policy in PDP Groups.
- PDP in tenant namespace needs to check during initialization that DB is ready in the central namespace.
- PDP → DB latency will increase if DB is in central namespace (Can be solved by splitting & moving DB to tenant namespace).
Scope for G H release

- Deploy/Undeploy policies to specific tenant based PdpGroup.
