Breaking Changes

None - this is a new feature addition with no impact on existing functionality.

Dependencies Added

  • Temporal SDK already in use (no new dependencies)
  • Uses existing PostgreSQL, NATS, and S3 client libraries

Remaining Work (Future PRs)

1. Comprehensive Tests (~1,700 lines estimated)

  • Unit tests for workflows, activities, service, repository
  • Integration tests with test containers (PostgreSQL, MinIO, NATS, Temporal)
  • gRPC handler tests
  • Middleware tests

2. Server Integration (~50 lines)

  • Register cleanup service in backend/cmd/server/main.go
  • Wire up dependencies (repository, location service, audit service, auth service)
  • Configure middleware stack
  • Add health check registration

3. Frontend (Future)

  • React admin interface for cleanup operations
  • Job monitoring dashboard
  • Real-time progress tracking

Deployment Notes

Prerequisites

  • PostgreSQL 15+ (for cleanup tables)
  • Temporal server (for workflows)
  • NATS + JetStream (for events)
  • S3-compatible providers (MinIO, Ceph RGW, or AWS S3)

Migration

# Run database migration
make migrate-up

Configuration

  • No new environment variables required
  • Uses existing location service for S3 credentials
  • Integrates with existing auth and audit services

Temporal Worker

  • Cleanup workflows must be registered with Temporal worker
  • See workflows.go for workflow definitions
  • Activities require location, audit, and auth service dependencies

Security Considerations

Threat Model

  • SSRF Prevention: All S3 operations go through validated location service
  • Authorization: RBAC enforced via middleware with break-glass support
  • Audit Trail: Immutable logging of all cleanup operations
  • Input Validation: All requests validated before processing
  • Credential Security: S3 credentials never exposed to clients

Break-glass Mode

  • Requires explicit justification (min 10 characters)
  • Time-bound elevation (configurable duration)
  • All actions flagged in audit logs
  • UI must show persistent banner during break-glass

Checklist

  • Code follows project style guidelines
  • All code compiles successfully
  • Documentation updated (3 comprehensive docs)
  • No breaking changes
  • Commit messages follow convention
  • Branch is up to date with main
  • Security considerations addressed
  • Provider abstraction properly implemented

discovering and cleaning up orphaned data, partial uploads, corrupt
objects, and storage issues across S3-compatible providers.

## Components Added

### 1. Protobuf API Definition (api/proto/cleanup/cleanup.proto)
- Complete CleanupService gRPC API (14 RPCs)
- Scan operations for orphaned uploads, corrupt objects, old versions
- Cleanup operations with dry-run support
- Storage analytics and provider diagnostics

- Ceph RGW adapter with RADOS awareness
- Generic S3 adapter for AWS S3 and unknown providers
- Provider factory for automatic adapter selection

### 3. Adapter Capabilities
**All Providers:**
- List and abort orphaned multipart uploads
- Storage usage analytics with age/class distribution
- Object integrity verification
- Bucket-level metrics
- Incomplete object detection

**MinIO-Specific:**
- Batch operations for efficiency
- Parallel processing where safe
- Detailed part-level analysis

**Ceph RGW-Specific:**
- RADOS pool performance considerations
- Off-peak scheduling recommendations
- Bucket indexing awareness

### 4. Documentation (docs/STORAGE_CLEANUP.md)
- Complete feature overview and architecture
- Security model and authorization requirements
- Break-glass mode integration
- Provider-specific implementations and optimizations
- Detailed operation guides with examples
- Best practices and troubleshooting
- API reference and future enhancements

## Key Features

### Security & Audit
- Requires SYSTEM_ADMIN role
- Break-glass mode for sensitive operations
- Immutable audit logging for all actions
- Time-bound elevated access

### Operations Supported
1. Orphaned multipart upload cleanup
2. Corrupt object detection and removal
3. Old version management (when versioning enabled)
4. Empty object identification
5. Comprehensive storage analytics

### Provider Support
- MinIO (optimized)
- Ceph RGW (RADOS-aware)
- AWS S3 (standard)
- Generic S3-compatible (fallback)

## Architecture Decisions

1. **Provider Abstraction**: CleanupAdapter interface allows
   provider-specific optimizations while maintaining consistent API

2. **Dry-Run First**: All destructive operations support dry-run mode

   Temporal workflows (to be implemented)

4. **Audit Trail**: All operations logged immutably for compliance
   and forensics

5. **Break-Glass Support**: Sensitive cross-tenant operations require
   explicit justification and time-bound elevation
