Webb6 apr. 2016 · As mentioned above, Kafka is fundamentally a replicated log service. It does not use AMQP or any other pre-existing protocol for communication. Instead, it uses a custom binary TCP-based protocol. It is very fast, even in a small cluster. It has strong ordering semantics and durability guarantees. WebbRelated to that, Kafka Streams applications with the Processor API are typically built as follows: Add source node (s) Add N number of processors, child nodes of the source node (s) (child nodes can have any number of parents) Optionally create StoreBuilder instances and attach them to the processor nodes to give them access to state stores
