Schema registry

[Łukasz M.]

Hello, we are planning to use the Confluent platform toolset in our systems.

I'm looking especially at the Schema Registry and have couple of questions about it.

• Is there a way to secure schema registry and have it only in readonly mode? I wish that in production nobody is able to publish schemas through the kafka serializer when publishing messages, and have only compatibility check, and have limited access on publishing schemas in the production environment. Similarly I want to lock ability to change compatibility modes on the schemas.
• During my own tests I see that the schema is published under name {topic}-value and I understand that the name is called a subject. What is the tie of a topic to a subject? is it by the convention of the subject name? If no, how do I make sure that a schema I will publish will be tied to a topic?
• Tying the the fact that we want to have 2 schema registries(dev and prod), what is the recommended way to deploy schemas

Thank you

Lucas
