> without having to setup partitions Without being limited by partitions. In Kafka your unit of parallelism is partitions but what happens when you don't care at all (or much) about ordering and just want to add or remove consumers to match your current load? Queue semantics. In Kafka the number of partitions can go up, but not down. And even when you do that the messages don't get split up to fill the new partition so you can't burn down a backup by adding more partitions or more consumers -- ope.
