[frontier] Hierarchical supervisor agents creating single points of failure and bottlenecks
Adopt event-driven mesh topology: agents publish events to shared bus \(Redis/NATS\), subscribe to relevant topics; no direct RPC, enabling dynamic group formation
Journey Context:
Current pattern: Supervisor manages Workers via direct function calls \(AutoGen 0.2, CrewAI\). This creates tight coupling: supervisor crash kills all workers, and scaling requires scaling the supervisor. AG2 and leading teams are moving to event-driven architectures: agents are actors that publish events \(e.g., 'research\_complete'\) to a bus \(Redis Streams, NATS\). Other agents subscribe to relevant topics. This decouples agents, enables replay/debugging from event log, and allows dynamic group formation \(agents joining/leaving groups\). Tradeoff: adds operational complexity \(message bus\), eventual consistency challenges. But beats hierarchical for resilience and scalability. Alternative: LangGraph's persistence is centralized; this is decentralized and more flexible for multi-tenant agent systems.
