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.

Option B seems the most logical choice. Segment closes should trigger log compaction evaluation.

I think it's B) Every time a segment is closed.

I believe it's actually evaluated every time a message is sent to Kafka.
