The CDF outputs to a data transport solution. Consumers send a subscription to the data transport solution for a given set of data, for example, a Kafka Topic, which the data transport solution then returns.

We describe the data transport solutions supported by the CDF here, however, we highly recommend Kafka and have described the many advantages of using Kafka here. The CDF has built-in support for Kafka integration, and we provide reference implementations in Kafka later in this document.
