One broker can be leader for many partitions. Partitions are not only used to scale the brokers but also to scale the clients. So in many cases it makes perfect sense to have many partitions running from the same broker. (Of course having only one broker in total means no HA etc., but I guess you understand that ;-))
Under normal circumstances there should be always a leader for each partition. But of course there might be always some "temporary" situations when there is no leader for sometime such as when failovers happen etc. Jakub On Wed, Oct 4, 2017 at 4:00 PM, Tomer Shavit <morpash...@gmail.com> wrote: > and i have an additional question, can partion be without leader ? and if > so, what does it mean ? > > ---------- Forwarded message ---------- > From: Tomer Shavit <morpash...@gmail.com> > Date: 2017-10-04 16:30 GMT+03:00 > Subject: Kafka - leadership > To: users@kafka.apache.org > > > Hi, > > I have a question regarding kafka. if i have cluster which contains only > one broker, and i have topic which contains 2 partions. does it mean that > the same broker will be the leader for those 2 partitions ? can broker be > the leader for more than one partition ? > > Thanks, > Tomer >
