Demos

This is a curated list of demos that showcase Apache Kafka® event stream processing on the Confluent Platform, an event stream processing platform that enables you to process, organize, and manage massive amounts of streaming data across cloud, on-prem, and serverless deployments.

Where to start

The best demo to start with is cp-demo which spins up a Kafka event streaming application using KSQL for stream processing, with many security features enabled, in an end-to-end streaming ETL pipeline with a source connector pulling from live IRC channels and a sink connector connecting to Elasticsearch and Kibana for visualizations. cp-demo also comes with a playbook and is a great configuration reference for Confluent Platform.

Full demo list

Secret Protection Y Y Secret Protection feature encrypts secrets in configuration files
Replicator Security N Y Demos of various security configurations supported by Confluent Replicator and examples of how to implement them

Build Your Own

As a next step, you may want to build your own custom demo or test environment. We have several resources that launch just the services in Confluent Platform with no pre-configured connectors, data sources, topics, schemas, etc. Using these as a foundation, you can then add any connectors or applications.

  • cp-all-in-one: This Docker Compose file launches all services in Confluent Platform, and runs them in containers in your local host.
  • cp-all-in-one-cloud: Use this with your pre-configured Confluent Cloud instance. This Docker Compose file launches all services in Confluent Platform (except for the Kafka brokers), runs them in containers in your local host, and automatically configures them to connect to Confluent Cloud.
  • Confluent CLI: For local, non-Docker installs of Confluent Platform. Using this CLI, you can launch all services in Confluent Platform with just one command confluent local start, and they will all run on your local host.
  • Generate test data: "Hello, World!" for launching Confluent Platform, plus different ways to generate more interesting test data for your topics

Additional documentation: Getting Started

Prerequisites

For local installs:

  • Download Confluent Platform 5.3
  • Env var CONFLUENT_HOME=/path/to/confluentplatform
  • Env var PATH includes $CONFLUENT_HOME/bin
  • Each demo has its own set of prerequisites as well, documented individually in each demo

For Docker: demos have been validated with
