kafka in action definitive guide
As we mentioned in the previous section about committing offsets, a consumer will want to do some cleanup work before exiting and also before partition rebalancing. If you know your consumer is about to lose ownership of a partition, you will want to commit offsets of the last event you’ve processed. If your consumer maintained a buffer with events that it only processes occasionally (e.g., the currentRecords map we used when explaining pause() functionality), you will want to process the events you accumulated before losing ownership of the partition. Perhaps you also need to close file handles, database connections, and such.
