 If your processing rate is high this might not be optimal since you'll be committing for each message, even if using async commits there's some degree of performance penalty.
 So another alternative is to keep `enable.auto.commit` set to True (default) but disable the automatic offset store.
 So what is the offset store?
 Each time a message is passed from the client to your application its offset is stored for future commit, the next intervalled commit will then use this stored offset. If the stored offset did not change from the last commit nothing happens.

 So by setting `enable.auto.offset.store` to False you keep the convenient intervalled auto commit behaviour but you control what offsets are actually eligible for commit.
