// In some situations it is hard to say whether records range (between two offsets) was fully polled.
// This happens when we have holes in records sequences that is usual case for compact topics or
// topics with transactional writes. In such cases if you want to poll all records between offsets X and Y
// there is no guarantee that you will ever see record with offset Y.
// To workaround this we can assume that after N consecutive empty polls all target messages were read.
