🔧 Technical Implementation Details

Database Migrations

Design Patterns:

• Abstract Base Class pattern for migrations
• Factory pattern for migration loading
• Strategy pattern for upgrade/downgrade
• Singleton pattern for migration history

Key Features:

• Automatic version tracking
• Rollback support with error handling
• Validation before execution
• Execution time tracking
• Success/failure logging

Migration Format:

class MyMigration(Migration):
    def __init__(self):
        super().__init__(
            version="YYYYMMDD_NNN",
            description="Clear description"
        )

    async def upgrade(self, session):
        # Forward migration
        pass

    async def downgrade(self, session):
        # Rollback migration
        pass

🎓 Lessons Learned

1. Migration System: Proper version tracking and rollback support are essential
2. Performance Testing: Async testing requires careful fixture management
3. Security Testing: Comprehensive payload libraries catch edge cases
4. Documentation: Good documentation is as important as the code itself
5. Testing: Testing frameworks should be created even if not immediately integrated
