Multi-Tenant

Multi-tenancy allows a single application instance to serve multiple customers (tenants) while keeping their data completely isolated.

Isolation Strategies

1. Database-Level

// Separate database per tenant
const db = getTenantDatabase(tenantId);
await db.query("SELECT * FROM users");

2. Schema-Level

-- Separate schema per tenant
SELECT * FROM tenant_123.users;
SELECT * FROM tenant_456.users;

3. Row-Level

-- Shared tables with tenant_id
SELECT * FROM users WHERE tenant_id = '123';

TrustGraph Multi-Tenancy

// Create isolated Knowledge Graph per tenant
await trustgraph.tenant.create({
  id: "company-abc",
  isolation: "graph",  // Separate graphs
  resources: {
    graphDb: "neo4j-abc",
    vectorDb: "qdrant-abc"
  }
});

// Query respects tenant isolation
const results = await trustgraph.query({
  tenantId: "company-abc",
  query: "MATCH (n) RETURN n"
  // Only sees company-abc's data
});

Benefits

• Cost Efficiency: Share infrastructure
• Easy Updates: Update once, all tenants benefit
• Resource Sharing: Better utilization
