Yes, I think that section of the protocol guide could be improved.
Specifically, it would be useful to explain what the " Time" and
"MaxNumberOfOffsets" parameters are used for, as well documenting these
two magic numbers (-1 and -2).

David,
The API that you are looking for is OffsetRequest. If you pass in -2 as the
value for Time, it will get you the earliest offset available for that
partition. If you pass in -1, it will get you the latest offset.
You can find more information about the OffsetRequest and OffsetResponse
APIs here -

Please let us know if that description can be improved.
Thanks,
Neha

Is there currently a way to get the latest offset (or close to the latest)
for a partition? Is this covered by the Offset API, and if so could someone
explain this API a bit?
I'd like to write a consumer that can start from 0 (like unix cat) or
start from the most recent (like unix tail).
Thanks!
