Schema Evolution

Concepts: paSchemaEvolution

What They Want to Hear 'I classify schema changes as additive or breaking. Adding a new column is additive and should be handled automatically. Renaming or removing a column is breaking and requires a migration plan. My pipeline detects schema drift on each run and either auto-adapts for additive changes or alerts the team for breaking ones.' That is the framework. Additive vs breaking. Auto-handle vs alert.
