[All CCDAK Questions]

In Avro, adding a field to a record without 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.

I thought it was full evolution, but now I'm not so sure.

I’m confused about this one. I thought it was full evolution, but now I’m leaning towards breaking since it affects compatibility.

I feel like this might be a backward schema evolution since older versions wouldn't know how to handle the new field.

I remember practicing a question about schema evolution, and I think adding a field is forward compatibility if it has a default value.

I'm not totally confident, but I think the answer is A. Forward schema evolution. The key is that the new schema is compatible with the old one, so it's a non-breaking change.

Okay, I've got this. Adding a field without a default is a forward schema evolution, because it allows the new schema to be read by older readers that don't have that field.

I'm pretty sure this is a forward schema evolution, since adding a field without a default value is considered a non-breaking change in Avro.

Hmm, I'm a bit confused on this one. I know schema evolution is important in Avro, but I can't remember the exact terminology for adding a field without a default. I'll have to think this through carefully.

This seems like a pretty straightforward question. The key is ensuring the database dumps complete before the SnapMirror update, so I'd say OnCommand Workflow Automation is the tool that can help automate that process.

Adding a field without a default? Sounds like a great way to 'Avro-id' compatibility issues. *ba dum tss*
