Subject Consumer's Group.id and autooffset.reset
Date Mon, 05 May 2014 12:28:42 GMT
Would some one explain the interplay between the group.id and autooffset.reset config parameters?
I wrote a simple Consumer that had

    group.id =  "XYZZY"
    autooffset.reset = smallest

My intention was to write something similar to Kafka's ConsoleConsumer; that each time my
Consumer ran, it would start at the beginning and read all of the messages available. I discovered
that it only read the messages the first time, and that I need to change the group.id and
reset to smallest.

A general question is why?
A specific question is: What are use cases where I would change the group.id, what are use
cases where I want it to remain the same?
