Hi Binita, When you use a group id with a high level consumer, the messages will be distributed among all consumers sharing the same group. So if you have 3 consumers sharing the same group, each will process 1/3 of the messages within the group. By contrast, if each of the same 3 consumers used a different group id, they would each see all of the messages.
Hope that helps, Steve On Mon, Feb 24, 2014 at 10:38 PM, Binita Bharati <binita.bhar...@gmail.com>wrote: > Hi all, > > I am referring to this e.g: > https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example. > > What is the consumer group ID being referred here ? > > Thanks > Binita > -- Steve Robenalt Software Architect HighWire | Stanford University 425 Broadway St, Redwood City, CA 94063 srobe...@stanford.edu http://highwire.stanford.edu
