> Often clients need to find out which offsets contain necessary data. One of the possible solutions would be to iterate with small fetch size. However, this still leads to unnecessary data being transmitted in case keys already reference searched data. The ability to fetch keys only would simplify search for the necessary offset.
> Of course, there can be other scenarios where consumer needs keys only, without message part.
