Using external registry for avro or protocol buffers

[franciscolopezsancho]

the UX

the developer may want to

1. create their schema from a local file
2. consume/update their schema from a registry. It has to be Kafka? https://docs.confluent.io/platform/current/schema-registry/schema_registry_onprem_tutorial.html#auto-schema-registration

Starting with local schemas

• 1A. When buildApp they might want to
  • 1A.1 upload the schema to registry
  • 1A.2 make sure the schema has no conflict with latest version of uploaded schema. Assuming this will be the version deployed in the cluster.
• 1B. When deploy app, is it necessary to check? after all has to be done with buildApp. But what about we try to deploy a rollback or anything of that sort. Would be still compatible? I think so

Starting with remote Schemas

• 2A. When writing the app. So they need a way to download it or should be always part of the source code? tempted for the later to avoid problems.1
• 2B. When buildApp same as 1A

problems:

1. if from one workstation that access to the schema uses style 2 and from the next workstation there's no access to the registry -> always add schemas in local?
