Diffusion Real-Time Event Stream
Introduction to Diffusion Real-Time Event Stream through a simple application using Diffusion Cloud and Apache Kafka.
A set of simple projects, illustrating production and consumption of foreign exchange (fx) data streams to and from Kafka clusters and Diffusion Cloud instance via the use of our Kafka Adapter.
Lesson 1: Publish event streams to Kafka cluster
Lesson 2: Fine-grained distribution of Kafka event firehose with Topic Views
Lesson 2 code example introduces the concept of Topic Views, a dynamic mechanism to map part of a server’s Topic Tree (data structure) to another. This enables real-time data transformation before sending it to subscribed clients as well as to create dynamic data models based on on-the-fly data (eg: Kafka firehose data).
Lesson 3: Security with Topic-level access control
Lesson 3 code example introduces the concept of Security and topic path permissions for fine-grained security management of your data structure. It also shows how to Subscribe to fx data using Diffusion Topic Views in order to consume what you need, not all the Kafka stream.

- host: host (“kafkagateway.us.diffusion.cloud” by default)
- user: ‘user’
- password: ‘password’
