SAMPLE QUESTION:

What happens for a consumer application when closing one of the consumers cleanly?

(Choose one)

1. The Kafka broker will notify the group coordinator that one consumer is leaving, and the group coordinator will trigger a rebalance immediately.

2. The consumer application will consume messages with one consumer less.

3. The consumer will notify the group coordinator that it is leaving, and the group coordinator will trigger a rebalance immediately.

4. The consumer application breaks with the exception NOT_ENOUGH_CONSUMERS.
   
   

What's your guess? Scroll below for the answer

Correct: 3.

The way consumers maintain membership in a consumer group and ownership of the partitions assigned to them is by sending heartbeats to a Kafka broker designated as the group coordinator (this broker can be different for different consumer groups). As long as the consumer is sending heartbeats at regular intervals, it is assumed to be alive, well, and processing messages from its partitions. Heartbeats are sent when the consumer polls (i. e., retrieves records) and when it commits records it has consumed.

When closing a consumer cleanly, the consumer will notify the group coordinator that it is leaving, and the group coordinator will trigger a rebalance immediately, reducing the gap in processing.
