Overview

The use case is a Kafka event streaming application for real-time edits to real Wikipedia pages. Wikimedia's EventStreams publishes a continuous stream of real-time edits happening to real wiki pages. Using Kafka Connect, a Kafka source connector kafka-connect-sse streams raw messages for the server sent events (SSE), and a custom Kafka Connect transform kafka-connect-json-schema transforms these messages and then the messages are written to a Kafka cluster. This example uses ksqlDB and a Kafka Streams application for data processing. Then a Kafka sink connector kafka-connect-elasticsearch streams the data out of Kafka and is materialized into Elasticsearch for analysis by Kibana. All data is using Confluent Schema Registry and Avro. Confluent Control Center is managing and monitoring the deployment.
