Q: if i successfully run a Flow/Task locally and now wanted to run the same flow/task in another remote cluster and I "register" the Flow/task with the Prefect server, its my understanding that only the Flow/Task DAG metadata got serialized to the Prefect Server/Database. My question is how does the full complement of the Flow/Task code and its third-party dependency libraries got deployed or loaded in the remote cluster? Am I missing something here? Who is the deploying the code to the remote cluster??
