What it shows

  • Producers check schema compatibility with the registry prior to publishing.
  • Backward compatibility guarantees existing consumers safely parse events.
  • Schema IDs are prepended to binary payloads to reduce message overhead.

The takeaway

Enforce schema contracts centrally to evolve event payloads safely without breaking downstream consumers.
