question about namesrv cluster up-scale #28

Closed keranbingaa closed 4 years ago

keranbingaa commented 4 years ago

when namesrv cluster up-scaling，does the broker shutdown and change the namesrv list and then restart? I have this question becuase I note the broker IP changed after namesrv cluster up-scale and the log file contians restart log. can we up-scale the namesrv cluster without restart broker?

liuruiyiyang commented 4 years ago

YES, when namesrv cluster up-scaling, the broker instances will rolling restart (one by one). Thus this process has little influence on providing service for user bussiness, unless you have only one broker instance. Could you please tell us more about what harms if the broker restart(broker IP changing) in your application scenario?
