Talk Structure: "Beyond Your ORM's Migration Tool"

  1. Introduction – Why ORMs Build Migration Tools

    • ORMs like SQLAlchemy and Django ORM simplify database interactions and include migration tools (e.g., Alembic, Django Migrations) for schema changes.
    • These tools are robust for ORM-defined schemas but lack advanced features and native CI/CD integrations.
  2. Where Built-in Tools Fall Short

    • ORM migration tools focus on basic schema changes but don’t support advanced database objects like triggers, materialized views, or stored procedures.
    • Lack native integration with modern CI/CD tools, leaving teams to implement custom, often suboptimal solutions.
  3. Presenting Atlas – Bridging the Gap

    • Atlas complements ORM tools by reading their schemas (e.g., Django models, SQLAlchemy models) and enabling advanced extensions.
    • Key features:
      • Support for triggers, materialized views, and other advanced objects.
      • Native CI/CD integration for automating and validating schema changes.
  4. How Atlas Integrates with ORMs

    • Atlas reads ORM-defined schemas and enhances them with advanced features.
    • Combines ORM workflows with Atlas’s robust schema management capabilities, enabling automation and database-specific optimizations.
  5. Demo – Atlas in Action

    • Example: A Django project adds a materialized view and a trigger using Atlas.
    • Steps:
      • Use Atlas to read the ORM schema and extend it with advanced features.
      • Automate migration validation and deployment through CI/CD pipelines.
    • Outcome: Simplified and automated schema management with modern tooling.
  6. Conclusion and Q&A

    • Key Takeaways:
      • ORM migration tools like Alembic and Django Migrations are great for standard use cases but fall short for advanced workflows and CI/CD integration.
      • Atlas bridges this gap, enabling automation and advanced database features.
    • Call to Action: Try Atlas to enhance schema workflows.
    • Q&A: Open floor for questions.
