What Is a Schema Registry Check?

A schema registry check is a CI step that submits a new or changed schema to a registry, or compares against it, to confirm the change respects compatibility rules. The registry stores the canonical schema versions for messages or APIs and enforces rules like backward or forward compatibility. A non-compatible change fails the check.

Why it matters

Validating schema changes against a registry in CI stops a producer from shipping a format that breaks existing consumers. It catches incompatible evolution before it reaches a shared topic or API.
