What is schema drift in data pipelines ?

It's when JSON structures change upstream without syncing downstream—nulls appear, fields vanish, silently breaking your systems.

How do you prevent malformed JSON in ingestion pipelines?

Use defensive validation libraries like Pydantic or Great Expectations at entry points, plus schema registries and contract tests.

Can schema drift really cost millions?

Yes—Gartner says poor data quality drains $12.9M-$15M yearly per org; drift incidents average $35k each, scaling fast in big ops.
