Solo (deprecated in v2.0) The Solo implementation of the ordering Although Kafka has many admirers, even those admirers will (usually) admit that deploying a Kafka cluster and its ZooKeeper ensemble can be tricky, requiring a high level of expertise in Kafka infrastructure group of hosts. This means that practically speaking you need to have one organization run the Kafka cluster. Given that, having ordering nodes run by different organizations when using Kafka (which Fabric
