    Hi **@hmcl**, in some project we are tracking the DB activities, we may need the message to be emitted in same sequence as they were polled from Kafka - i.e. polled 5 messages(1~5), if 1, 3, 4, 5 was acked while 2 is failed, seems currently only 2 will be re-emitted , this will cause the sequence is like 1, 3, 4, 5, 2..is it possible to re-emit message from the position that was failed, so the flow will be: 1, 3, 4, 5, 2, 3, 4, 5...
    What is your view on this?
