You are connecting to a single seed node - your kafka library will then under the hood connect to the partition leaders for each partition you subscribe or post to.
The load is not different compared to if you gave all nodes as connect parameter. However if your seed node crashes then your client cannot connect to the cluster.,. 2017-11-28 15:06 GMT+01:00 Skip Montanaro <skip.montan...@gmail.com>: > Apologies for the rather long set-up... > > I've been using Kafka as a client for a few months now.
