MVP Articles

This page brings together externally published articles written by our MVPs. Discover expert perspectives, real-world guidance, and community contributions from leaders across the ecosystem.

The official Databricks Apps quickstart puts everything into a single app.py. Fine for a demo — painful once the app grows past ~500 lines.

Problems with the single-file pattern:

Merge conflicts on every PR
UI, logic, and SDK calls coupled → no unit tests
Unreadable diffs in code review
AI assistants (Cursor, Claude) re-parse the whole file every prompt → high token cost
