?My understanding is that the group id indicated to a consumer constructor is 
an arbitrary string of my own choosing on the client side, at the time of 
construction, which will "group" committed offsets for any set of such 
consumers.  But the offsets() function, which is merely a query function for 
seeing the current offsets, is defined as taking a "group" parameter which is a 
string chosen from the set a set of constants: fetch, commit, task_done, or 
highwater (alternatively the function can be called with no parameter in which 
all four values are returned).


Am I correct that the use of the term group in these two cases is absolutely, 
totally unrelated?
