Schema Registry

A central service for storing, versioning, validating, and discovering schemas used by data streams and messages.

Why it matters

Schema Registry helps data teams design systems that are reliable, understandable, governable, and efficient at scale.

Design considerations

• Define ownership, contracts, and expected consumers.
• Make failure, replay, compatibility, and observability behavior explicit.
• Measure quality, freshness, cost, and operational burden rather than optimizing only throughput.
