when I add partitions in topic after creation, do restart of producers required?
I am using java producers and messages are keyed messages, so when total no of partitions change do we need to restart producers or it gets no of current partitions in each send call? As per org.apache.kafka.common.utils.Utils.Cluster it seems partitions info is cached at first time only ? 2.Since in kafka a partition is not divided among brokers so what if one broker's disk gets full, do it stop taking new messages till new ISR becomes leader for this partition ? And what if same situtaion happens and my message is not keyed rather roundrobin ? Does it fails the write if round robined broker is out of disk or it writes to any other broker?
