How are modifications to the same key treated in an append-only source like Kafka? Is there an upsert option based on the key?
I'm curious about how modifications to the same key are handled in an append-only source like Kafka. Additionally, I would like to know if there is an upsert option based on the key.

Yes, modifications to the same key in an append-only source like Kafka can be treated as upserts if you declare the key as a primary key in the create source statement.
