Sprint 3 Complete - Cloud Storage Full Implementation:
New Features:
✅ Multipart upload for large files (>100MB)
✅ Automatic part size (10MB) and concurrency (10 parts)
✅ MinIO testing infrastructure
✅ Comprehensive integration test script
✅ Complete cloud storage documentation
New Files:
- CLOUD.md - Complete cloud storage guide (580+ lines)
- docker-compose.minio.yml - MinIO + PostgreSQL + MySQL test setup
- scripts/test_cloud_storage.sh - Full integration test suite
Multipart Upload:
- Automatic for files >100MB
- 10MB part size for optimal performance
- 10 concurrent parts for faster uploads
- Progress tracking for multipart transfers
- AWS S3 Upload Manager integration
Testing Infrastructure:
- docker-compose.minio.yml:
* MinIO S3-compatible storage
* PostgreSQL 16 test database
* MySQL 8.0 test database
* Automatic bucket creation
* Health checks for all services
- test_cloud_storage.sh (14 test scenarios):
1. Service startup and health checks
2. Test database creation with sample data
3. Local backup creation
4. Cloud upload to MinIO
5. Cloud list verification
6. Backup with cloud URI
7. Database drop for restore test
8. Restore from cloud URI
9. Data verification after restore
10. Cloud backup integrity verification
11. Cleanup dry-run test
12. Multiple backups creation
13. Actual cleanup test
14. Large file multipart upload (>100MB)
