Core Concepts

What is Alembic?

Alembic is a lightweight database migration tool for use with SQLAlchemy. It provides a way to manage changes to your database schema over time through version-controlled migration scripts. For customer support systems, this means:

• Version Control: Track all schema changes in your support database
• Reproducibility: Apply the same migrations across dev, staging, and production
• Rollback Capability: Safely revert problematic changes
• Team Collaboration: Merge schema changes from multiple developers
• Data Preservation: Migrate data during schema transformations
