Show Suggested 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.

Wait, so the connector is deployed on a cluster of 3 workers, but the max.tasks is set to 2? That's like putting a Ferrari engine in a Prius, what's the point?
