Story 2: Audit Log Core Features (Phase 2)
Sprint: Sprint 2 Priority: P0 (Must Have) Estimated: 3-4 days (Day 27-30) Owner: Backend Team
Description
Enhance audit logging with core features including changed fields detection (old vs new values JSON diff), user context tracking, multi-tenant isolation, query API, and integration tests.
Acceptance Criteria
- Changed fields tracking implemented with JSON diff
- User context (UserId) automatically captured
- Multi-tenant isolation for audit logs enforced
- Query API implemented for retrieving audit history
- Integration tests with >= 90% coverage
- Performance target met (< 5ms overhead)
- All tests passing
Technical Requirements
Enhanced Features:
- Changed Fields Detection: Compare old vs new values, store only changed fields
- User Context: Automatically capture current user from HTTP context
- Multi-Tenant Isolation: Filter audit logs by TenantId
- Query API: REST endpoints for audit history retrieval
Technology Stack:
- System.Text.Json for JSON diffing
- PostgreSQL JSONB for flexible storage
- CQRS pattern for query handlers
Tasks
- Task 1 - Implement Changed Fields Detection (JSON Diff)
- Task 2 - Integrate User Context Tracking
- Task 3 - Add Multi-Tenant Isolation
- Task 4 - Implement Audit Query API
- Task 5 - Write Integration Tests
Progress: 0/5 tasks completed
Dependencies
Prerequisites:
- ✅ Story 1 completed (Audit Log Foundation)
- ✅ EF Core Interceptor implemented
- ✅ AuditLog entity and repository ready
Definition of Done
- All 5 tasks completed
- Changed fields detection working correctly
- User context captured from HTTP context
- Multi-tenant isolation verified
- Query API endpoints working
- All tests passing (>= 90% coverage)
- Performance benchmark met (< 5ms overhead)
- Code reviewed and approved
- Git commit created
Notes
Performance Target: < 5ms overhead per SaveChanges operation JSON Diff: Store only changed fields, not full entity snapshots (storage optimization)
