What this project needs to run:

1. Kafka on localhost:9092
2. postgresql on localhost:5432

(docker compose in /docker)

How to reproduce the issue:

1. Start the project

2. curl http://localhost:8080/test-ok
   (new record in DB y kafka -> ok)

3. STOP kafka

4. curl http://localhost:8080/test-ok
   (new record in DB!! -> not ok)

• Expected result after step 3: is no records to be found in DB (and Kafka). Everything should be rollback.
• Actual result: there are new record in DB.
