Event-Driven Hierarchical Agents(EDHA)
Multi-level agent hierarchy with event-based coordination
In 30 seconds
- What
- Organizes agents in levels where each tier consumes events, decomposes work, and publishes to the next tier's topic.
- When to use
- Large organizations with clear reporting structures need task delegation, isolation of failures, and independent scaling per level.
- Watch out
- Event propagation delays and cascading failures across levels become hard to debug; misconfigured topics cause work to vanish silently.
