Mmmm you are right. Even if I had 1000 components spread in different project modules, only those components that are imported in the script where the pipeline is defined would be included in the DAG plot, is that right?

Mmm I see. However I think that only the components used for that pipeline should be shown, as it may be the case that you have defined, say, 1000 components, and you only use 10 in a pipeline. I think that listing them all would just clutter up the results tab for that pipeline task

why are all defined components shown in the UI Results/Plots/PipelineDetails/ExecutionDetails section? Shouldn't it make more sense to show only the ones that are used in that pipeline?

They are listed there (because of the decorator, you basically "say" these are steps so they are listed), the actual resolving (i.e. which steps are actually being called) is done in "real-time"
Make sense ?

GiganticTurtle0 in the PipelineDecorator.component , did you pass helper_functions=[] with refrence to all the sub component ?

Only those components that are imported in the script where the pipeline is defined would be included in the DAG plot, is that right?

Actually the way it works currently (and we might change it if there is a better way), every time you call PipelineDecorator.component a new component is stored on the Pipeline Task, which is later translated into DaG graph and Table (next version will have a very nice UI to display / edit them).
The idea is first to have a representation of the pipeline process, before it is launched, the second is to allow you to edit the DaG in the UI:
Create pipeline from code Clone in UI Edit configuration to change the pipeline parameters, for example change target execution queue for indevidual stepsMake sense ?

I think that listing them all would just clutter up the results tab for that pipeline task

Can you share a screen so we better understand the clutter ?
Also "1000 components" ?! and not using them ? could you expand on how/why?
