> As far as I understand, at the current moment, there is no reliable way for getting offset of the last record in the partition using java client. There is {{endOffsets}} method in the consumer. And usually {{endOffsets - 1}} works fine. But in the case of transactional producer, topic may contain offsets without a record. And {{endOffsets - 1}} will point to the offset without record.
> This feature will help in situations when consumer application wants to consume the whole topic. Checking of beginning and last record offset will give lower and upper bounds for consuming. Of course, it is doable with the current consumer implementation, but I need to check {{position}} after each poll.
> Also, I believe that this feature may help with monitoring and operations.
