In Avro, adding an element to an enum without a default is a __ schema evolution

Show Suggested Answer Hide Answer
Suggested Answer: A

Since Confluent 5.4.0, Avro 1.9.1 is used. Since default value was added to enum complex type , the schema resolution changed from:

(<1.9.1) if both are enums:** if the writer's symbol is not present in the reader's enum, then an error is signalled. **(>=1.9.1) if both are enums:

if the writer's symbol is not present in the reader's enum and the reader has a default value, then that value is used, otherwise an error is signalled.

Gotta be B. Full schema evolution is the only way to ensure our data stays pristine, right? Anything else is just asking for trouble.

Hmm, I'm not so sure. This seems more like a full schema evolution to me. Avro is tricky, man.

I agree with Lanie, C) backward makes more sense in this context.

No, I believe it's C) backward because adding an element without a default is not breaking the existing schema.

Definitely C. Backward schema evolution is the way to go here. We don't want to break existing applications, do we?

I think the answer is D. Adding an element to an enum without a default is a forward schema evolution, as it allows new consumers to read the new enum values but maintains compatibility with older consumers.
