解説

When set to true, the 本製品 enables Kafka's idempotent producer mode. Kafka assigns a sequence number to each produced message, allowing the broker to detect and discard duplicates and to preserve message order during retries.

When set to false, the 本製品 does not apply these delivery guarantees, and duplicate messages may be produced if retries occur during network interruptions or broker failures.
