Resolution: Fixed

>
> The internal graph.Graph representation is used to unify user pipeline and
> the runtime subgraph. Perhaps we should instead translate the bundle
> descriptors directly to an execution plan (=
> []exec.Unit, but a encapsulating type seems useful). Aside: we would likely
> also need to have them be re-usable across bundles serially.
> Such a change would keep the construction-time and runtime worlds more apart
> instead of trying to unify them and we could remove DataSource/DataSink from
> the graph. The direct runner would then only translate a graph.Graph to
> []Unit and not have an awkward injection point for a DataManager.
