Hi Michael, Kafka spout is given parallelism-hint as 1 and the topic has only one partition. So, only one kafka spout task is run in one of the workers of the topology. Are you asking that bolts connected directly/indirectly from that kafka spout are all executed in the same worker as kafka spout? If so, What are the groupings and parallellism-hint that you have configured on those bolts?
