Which property controls the interval at which Kafka auto-commits offsets?

• A. auto.offset.reset
• B. retry.backoff.ms
• C. auto.commit.interval.ms
• D. enable.auto.commit

Answer: (C)

This question is about how often the Kafka consumer saves its progress automatically. When autocommit is turned on, the consumer periodically commits the offsets it has processed for each partition. The timing of those automatic commits is controlled by a single setting: auto.commit.interval.ms, which sets the interval in milliseconds between commits. For example, setting it to 5000 means the consumer will attempt to commit offsets roughly every five seconds while running. The other options serve different purposes: enable.auto.commit toggles whether autocommit is enabled at all; auto.offset.reset decides where to start if there’s no committed offset or the offset is out of range; retry.backoff.ms determines how long to wait before retrying a failed request, not the commit interval.
