Major Architecture Restructuring: Data Director Group Classification

This release introduces a fundamental transformation in the OCNADD architecture. The previously singular Worker Group has been decoupled and re-architected into two specialized functional groups: the Relay Agent Group and the Mediation Group.

This architectural shift impacts the entire system workflow and is reflected throughout this document. The following sections have been significantly revamped:

  • Refined Architecture Overview:
    • The "Architecture" and "Overview" sections now detail the three-group structure: Management Group, Relay Agent Group, and Mediation Group.
    • New high-level diagrams illustrate the data flow between the Relay Agents and the Mediation layer, separate from the Management layer.
  • Group-Specific Configuration Procedures:
    • Configuration procedures are no longer generic to a "Worker Group." All setup procedures are now distinct for Relay Agent nodes and Mediation nodes or namespaces.
  • Updated Observability (KPIs, Metrics, & Dimensions):
    • KPIs, Metrics, Dimensio, and Alerts: Performance indicators have been recalibrated. You will now see distinct metrics for throughput Relay Agents, separate from Mediation.
