ddd4j-cloud Tenant

Overview

Covers the Tenant annotation, TenantContextHolder, system isolation, data scope, SQL, and cross-service propagation uniformly, not split per artifact. Choose the Cloud→Boot→ddd4j primary combination first, then read the current branch.

When to Use

• Wiring the Tenant annotation and TenantContextHolder at request entry in a ddd4j-cloud service.
• Applying data scope and tenant SQL filtering, and deciding which tables are exempt.
• Writing or auditing tenant ignore rules for system and background operations.

• Diagnosing cross-tenant data leaks or reads returning another tenant's rows.
