Before being able to spin up the docker-compose based demo environment please make sure to successfully build all 4 projects - the petclinic monolith based on Spring, the owner microservice powered by Quarkus, the custom Flink functions as well as the Flink table joiner application:
./build-applications.sh
Spin up the demo environment by means of Docker compose.
- If you want to run the demo using Kafka Connect with Debezium and source the Flink Table API application from Kafka topics run it with
docker compose -f docker-compose-table-api-kafka-dbz.yaml up
- Otherwise, the demo can also Flink CDC based on Debezium to directly source the Flink SQL application from the database. To do so, run it with:
docker compose -f docker-compose-sql-flink-cdc.yaml up
There is a simple, yet convenient script which allows to run through the demo step-by-step. Once the docker compose stack is successfully up just run the demo in either of the two provided modes:
- Debezium with Kafka Connect and Flink Table API application:
./execute_demo_steps.sh kafka-dbz
- Flink CDC based on Debezium with Flink SQL application:
./execute_demo_steps.sh flink-cdc
