The service is under active development tackling challenging problems of scale:
•
Find and build innovative ways to grow traffic and data 10x within a limited resource footprint
•
Significantly simplify onboarding and operations for clients
•
Rethink the core muppet/union systems as they relate to serving the graph at global scale
Define the roadmap and drive the development of Topic Server APIs (how clients use Topic Server) and Frameworks (infrastructure/tool we should use for development and operation).
Lead projects to provide continuous, relevant answers to questions about Knowledge Graph data usage which informs resource efficiency and service tiering.
