Data Flow

  1. Agent action → Local AgentDB (0.1ms - fast!)
  2. Sync → Supabase PostgreSQL (25ms)
  3. CDC → Real-time broadcast to all agents
  4. Event → Other agents receive and process
  5. Update → Agents update local cache

🎯 Usage Example

import { createRealtimeHub } from 'agentic-flow/federation/integrations/realtime-federation';

// Create agent
const agent = createRealtimeHub('my-agent', 'my-team');
await agent.initialize();

// Listen for messages
agent.on('message:received', (msg) => {
  console.log('Received:', msg.payload);
});

// Broadcast to team
await agent.broadcast('status_update', {
  status: 'Working on task',
  progress: 0.75
});

// Get active team members
const team = agent.getActiveAgents();
console.log(`Team size: ${team.length} agents online`);
