Kafka consumer group rebalance
Why can a Kafka consumer group experience a temporary processing pause?
Options
- 1Broker restarts delete the topics, so the consumers must pause until the topics are fully recreated again
- 2Consumers must re-download all of the messages from the very beginning before they can resume their work
- 3A rebalance reassigns partitions among consumers when membership changes, and processing pauses until the new assignment completes
- 4The log is compacted on every rebalance, which pauses the consumers until that compaction finally finishes
