Schema Contracts

Concepts: paSchemaEvolution

What They Want to Hear 'I treat schema evolution as a platform service, not a per-pipeline concern. Producers publish a schema contract that defines the fields, types, and compatibility guarantees. Consumers register their dependencies. The platform enforces compatibility rules at publish time: if a proposed change would break a registered consumer, the publish is rejected. This shifts schema validation from runtime failures to build-time rejections.' This is the answer that shows you think about schema evolution as an organizational problem, not just a technical one.
