Kafka Event Streaming Applications
This demo and accompanying tutorial show users how to deploy an Apache Kafka® event streaming application using ksqlDB and Kafka Streams for stream processing. All the components in the Confluent platform have security enabled end-to-end. Run the demo with the tutorial.

Overview
The use case is a Kafka event streaming application for real-time edits to real Wikipedia pages.
Wikimedia Foundation has IRC channels that publish edits happening to real wiki pages (e.g. #en.wikipedia, #en.wiktionary) in real time.
Using Kafka Connect, a Kafka source connector kafka-connect-irc streams raw messages from these IRC channels, and a custom Kafka Connect transform kafka-connect-transform-wikiedit transforms these messages and then the messages are written to a Kafka cluster.
This demo uses ksqlDB and a Kafka Streams application for data processing.
Then a Kafka sink connector kafka-connect-elasticsearchstreams the data out of Kafka, and the data is materialized into Elasticsearch for analysis by Kibana.
Confluent Replicator is also copying messages from a topic to another topic in the same cluster.
All data is using Confluent Schema Registry and Avro.
Confluent Control Center is managing and monitoring the deployment.
