How often is log compaction evaluated?

BEvery time a segment is closed

DEvery time a message is flushed to disk

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.

I'm voting for Option B. It's the only one that makes sense from an operational perspective.

Option A is interesting, but I don't think creating a new partition should automatically trigger log compaction.

That's correct, log compaction occurs every time a segment is closed.

Option C is just silly. Log compaction has nothing to do with message sending in Kafka.

I'm not sure if Option D is correct. Flushing a message to disk doesn't necessarily mean it's time for log compaction.

Hmm, I see. That makes sense too, since Kafka needs to keep track of messages being sent.

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