From: Paul Cavallaro To: users@kafka.apache.org Content-Type: multipart/alternative; boundary=94eb2c123022fc7eae0531912b8e --94eb2c123022fc7eae0531912b8e Content-Type: text/plain; charset=UTF-8 Hey All, Was wondering what happens in the case of having a cluster where brokers' server.properties files differ. That is, what happens if Broker1 has default.replication.factor=3 and Broker2 has default.replication.factor=1. If I issue a create topic command w/o specifying the replication level, do I get 1 or 3 depending on which Broker is the Controller? Which Broker serviced the request (not sure what this would mean, sorry)? Which Broker was assigned to be the Partition Leader? This gets more interesting of course when you consider settings like unclean.leader.election. Does it just matter what the server.properties of the current Controller are? Thanks for any info on the matter. -Paul --94eb2c123022fc7eae0531912b8e--
