Summary
In dynamic systems, schemas evolve as new requirements emerge.
Fields are added, structures change, and coding systems are updated.
Without controlled schema evolution, this introduces instability across pipelines.
Ingestion processes break, transformations fail, and datasets become inconsistent across versions.
This is often treated as a maintenance issue, but it is architectural.
Systems must support:
- schema versioning and compatibility management
- controlled rollout of schema changes
- backward compatibility across pipelines
Schema evolution must be managed explicitly.
Otherwise, it becomes a continuous source of system failure.
