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.

Nah, it's a full schema evolution. Avro's just going all-in, no half-measures here.

I agree with Edgar, adding an element without a default is forward schema evolution.

C'mon, it's gotta be backward. Avro's all about that old-school compatibility, you know?

Forward schema evolution, huh? Sounds like Avro is trying to keep us on our toes. Gotta stay ahead of the game, am I right?

Adding an element to an enum without a default is definitely a breaking schema evolution. Avro isn't playing around with this one!
