1. Start containers

docker-compose up

2. Start debezium

for name in cassandra-seed cassandra1 cassandra2; do docker-compose exec -d $name sh start-debezium.sh; done

This can take some time as cassandra takes some time to start.

3. Make changes

cqlsh localhost 9042

4. Verify events on debezium logs

for name in cassandra-seed cassandra1 cassandra2; do docker-compose exec $name cat debezium.stdout.log | grep -i "Received event"; done
