CI/CD for Data

Concepts: paCiCd

What They Want to Hear 'Every PR triggers: linting, unit tests, schema validation (fast, seconds). On merge to main: integration tests in staging (minutes). Before release: data diff on a staging subset (optional, hours). On deploy: canary rollout if the change affects critical pipelines.' The key insight: fast checks on every push, slow checks before release. Never skip the fast checks.
