This KSQL ratings demo showcases Kafka stream processing using KSQL. This demo was initially created for a KSQL workshop.

You can follow the step-by-step guide workshop instructions here. These instructions are based on Docker instead of your local Confluent Platform install.

• Common demo prerequisites
• Confluent Platform 5.0
• If you are running the step-by-step guide
  • Docker
  • Docker Compose
  • 8GB+ RAM

After you start the confluent platform (see the step-by-step guide for details).

• If you are running Confluent Platform, open your browser and navigate to the Control Center web interface Monitoring -> Data streams tab at http://localhost:9021/monitoring/streams to see throughput and latency performance of the KSQL queries
• If you are running Confluent Platform, use Control Center to view and create KSQL queries. Otherwise, run the KSQL CLI ksql http://localhost:8088.
