Is there a concurrency issue?

Is there a concurrency issue with calling the model interface directly in the flask? For example, when multiple clients call the interface at the same time, the model performs multiple operations at the same time.

Concurrency is not supported. If you want multiple users to access your application, you need to be careful.

1. you can have a master node that distributes request to different slaves nodes
2. each slave node can have a buffer / queue with pending requests that gets unpiled.
