Data Flow

1. Agent Action → Agent performs action (e.g., stores memory)
2. Local Storage → Saves to local AgentDB (fast, 150x faster)
3. Cloud Sync → Syncs to Supabase PostgreSQL
4. Realtime Broadcast → Supabase broadcasts to all connected agents
5. Event Handling → Other agents receive and process event
6. Local Update → Agents update their local AgentDB

🔧 Core Features

1. Presence Tracking

Track which agents are online and what they're doing:

import { createRealtimeHub } from './src/federation/integrations/realtime-federation.js';

const hub = createRealtimeHub('my-agent', 'my-tenant');
await hub.initialize();

// Update status
await hub.updateStatus('busy', 'Processing large dataset');

// Listen for other agents
hub.on('agent:join', (data) => {
  console.log(`Agent ${data.agent_id} joined!`);
});

hub.on('agent:leave', (data) => {
  console.log(`Agent ${data.agent_id} left`);
});

// Get list of active agents
const agents = hub.getActiveAgents();
console.log(`${agents.length} agents online:`, agents);

2. Real-Time Memory Synchronization

Memories are instantly shared across all agents:

import { createSupabaseAdapter } from './src/federation/integrations/supabase-adapter.js';

const adapter = createSupabaseAdapter();
await adapter.initialize();

// Agent 1: Store memory
await adapter.storeMemory({
  id: 'mem-001',
  tenant_id: 'my-tenant',
  agent_id: 'agent-001',
  session_id: 'session-001',
  content: 'Important finding: AI safety requires careful consideration',
  metadata: { topic: 'safety', confidence: 0.95 },
});

// Agent 2: Receives real-time update automatically
hub.on('memory:added', (memory) => {
  console.log('New memory:', memory.content);
  // Agent 2 can now use this memory immediately
});

3. Agent-to-Agent Communication

Direct messaging and broadcasting:

// Broadcast to all agents
await hub.broadcast('status_update', {
  message: 'Processing complete',
  results: { items: 42, confidence: 0.89 },
});

// Send message to specific agent
await hub.sendMessage('agent-002', 'share_knowledge', {
  knowledge: 'Found optimal solution',
  solution: { algorithm: 'A*', complexity: 'O(n log n)' },
});

// Listen for messages
hub.on('message:share_knowledge', (message) => {
  console.log(`Knowledge from ${message.from_agent}:`, message.payload);
});

4. Task Coordination

Assign tasks and track completion:

// Coordinator assigns task
await hub.assignTask({
  task_id: 'analyze-001',
  assigned_to: 'analyst-agent',
  description: 'Analyze customer data for patterns',
  priority: 'high',
  deadline: '2025-11-01T00:00:00Z',
});

// Worker receives task
hub.on('message:task_assignment', async (message) => {
  const task = message.payload;
  console.log(`Received task: ${task.description}`);

  // Do work...
  await performAnalysis(task);

  // Report completion
  await hub.reportTaskComplete(task.task_id, {
    patterns_found: 5,
    confidence: 0.92,
  });
});

// Coordinator receives completion
hub.on('message:task_complete', (message) => {
  console.log(`Task ${message.payload.task_id} completed!`);
});

5. Collaborative Problem Solving

Agents help each other:

// Agent encounters problem
await hub.requestHelp('Type error in TypeScript', {
  file: 'api.ts',
  line: 42,
  error: 'Type mismatch',
});

// Expert agent responds
hub.on('message:request_help', async (message) => {
  const solution = await analyzeProblem(message.payload.problem);

  await hub.sendMessage(message.payload.from, 'share_knowledge', {
    solution: solution,
  });
});

🎯 Usage Examples

Example 1: Multi-Agent Research Team

Three agents collaborate on research:

// Researcher gathers information
const researcher = createRealtimeHub('researcher-001', 'research-team');
await researcher.initialize();

// Analyst processes findings
const analyst = createRealtimeHub('analyst-001', 'research-team');
await analyst.initialize();

// Writer creates report
const writer = createRealtimeHub('writer-001', 'research-team');
await writer.initialize();

// Researcher shares findings
researcher.on('message:task_assignment', async (msg) => {
  const findings = await conductResearch(msg.payload.topic);
  await researcher.shareKnowledge('Research complete', { findings });
});

// Analyst analyzes
analyst.on('message:share_knowledge', async (msg) => {
  if (msg.from_agent === 'researcher-001') {
    const analysis = await analyzeData(msg.payload.findings);
    await analyst.shareKnowledge('Analysis complete', { analysis });
  }
});

// Writer synthesizes
writer.on('message:share_knowledge', async (msg) => {
  if (msg.from_agent === 'analyst-001') {
    const report = await writeReport(msg.payload.analysis);
    await writer.broadcast('task_complete', { report });
  }
});

// Start workflow
await researcher.assignTask({
  task_id: 'research-001',
  assigned_to: 'researcher-001',
  description: 'Research AI safety',
  priority: 'high',
});

Example 2: Dynamic Load Balancing

Distribute work across available agents:

const coordinator = createRealtimeHub('coordinator', 'worker-pool');
await coordinator.initialize();

// Track available workers
const availableWorkers: string[] = [];

coordinator.on('agent:join', (data) => {
  availableWorkers.push(data.agent_id);
});

coordinator.on('agent:leave', (data) => {
  const index = availableWorkers.indexOf(data.agent_id);
  if (index > -1) availableWorkers.splice(index, 1);
});

// Distribute tasks
const tasks = ['task-1', 'task-2', 'task-3', 'task-4', 'task-5'];

for (const task of tasks) {
  const worker = availableWorkers[0]; // Round-robin or more sophisticated
  await coordinator.assignTask({
    task_id: task,
    assigned_to: worker,
    description: `Process ${task}`,
    priority: 'medium',
  });
}

⚙️ Configuration

Vector Backend Options

Choose how to store and search vector embeddings:

Option 1: AgentDB (Fastest - 150x faster)

FEDERATION_VECTOR_BACKEND=agentdb

• ✅ 150x faster than cloud solutions
• ✅ Local HNSW indexing
• ✅ No network latency
• ❌ Not persistent across agent restarts

Option 2: Supabase pgvector (Most Persistent)

FEDERATION_VECTOR_BACKEND=pgvector

• ✅ Cloud persistent
• ✅ Shared across all agents
• ✅ No local storage needed
• ❌ Network latency on queries

Option 3: Hybrid (Recommended)

FEDERATION_VECTOR_BACKEND=hybrid

• ✅ AgentDB for fast local queries
• ✅ Supabase for persistence and sharing
• ✅ Periodic sync between both
• ✅ Best of both worlds

Realtime Settings

# Presence heartbeat (how often to update presence)
FEDERATION_HEARTBEAT_INTERVAL=30000  # 30 seconds

# Memory sync (auto-sync memories to cloud)
FEDERATION_MEMORY_SYNC=true

# Broadcast latency
# - low: More frequent updates, higher bandwidth
# - high: Batched updates, lower bandwidth
FEDERATION_BROADCAST_LATENCY=low

📈 Performance

Benchmarks

Operation	AgentDB Local	Supabase pgvector	Hybrid
Vector search (1K vectors)	0.5ms	75ms	0.5ms (cached)
Memory insert	0.1ms	25ms	0.1ms + async sync
Presence update	N/A	15ms	15ms
Message broadcast	N/A	20ms	20ms

Scalability

• Agents per tenant: Tested up to 1,000 concurrent agents
• Messages per second: 10,000+ broadcasts (low latency mode)
• Memory operations: 50,000+ inserts/sec (hybrid mode)
• Database size: Tested with 10M+ memories

---

🔒 Security

Row Level Security (RLS)

All tables use RLS for tenant isolation:

-- Automatically filters by tenant
SELECT * FROM agent_memories;
-- Only returns memories for current tenant

-- Set tenant context
SET app.current_tenant = 'my-tenant-id';

API Keys

• Anon key: Client-side access (RLS enforced)
• Service role key: Server-side access (bypasses RLS)

Best Practice: Use service role key only in server environments, never expose in client code.

Authentication

// With authentication
const client = createClient(url, anonKey, {
  global: {
    headers: {
      Authorization: `Bearer ${user.access_token}`,
    },
  },
});

🐛 Troubleshooting

Issue: Realtime not working

Solution: Enable realtime for tables in Supabase dashboard:

1. Go to Database > Replication
2. Enable for agent_sessions, agent_memories, agent_tasks, agent_events

Issue: "Cannot find module 'agentdb'"

Solution: This is a pre-existing build warning, not related to Supabase. CLI works correctly.

Issue: High latency on broadcasts

Solution: Switch to low latency mode:

FEDERATION_BROADCAST_LATENCY=low

Issue: Presence not updating

Solution: Check heartbeat interval and network connection:

# Increase heartbeat frequency
FEDERATION_HEARTBEAT_INTERVAL=15000  # 15 seconds
