superfluous arrow in instavote diagram?
At https://trainingportal.linuxfoundation.org/learn/course/gitops-continuous-delivery-on-kubernetes-with-flux-lfs269/kubernetes-essentials-for-a-gitops-practitioner/kubernetes-for-gitops?page=8 at 2:41 an arrow is drawn from the PostgreSQL deployment to the result ui deployment, as if the PostgreSQL deployment connects to the service of the result ui deployment.
The same arrow is drawn at https://trainingportal.linuxfoundation.org/learn/course/gitops-continuous-delivery-on-kubernetes-with-flux-lfs269/kubernetes-essentials-for-a-gitops-practitioner/kubernetes-for-gitops?page=9
Should the connection from the PostgreSQL deployments to the service of the result ui deployment be omitted?

Hi @sanderhollaar,
The result services works with the database in a client-server way/protocol, so the result service includes a sql client that makes a SQL query to the PostgreSQL database. Then some processes are ran in the database and it's the database itself the one that replies to the result service. So, in this case the arrows are intended to show that type of communication, and are okey.
For more information about how this work, you can check on the source code of the instavote application, in the result service.
Regards,
