Description

Currently depends waits for either all inbound edges or one inbound edge. Using
depends: [parentnode]
or
depends:[parentnode_*]

I would like to wait for a subset of inbound edges chosen based on parameters. For example
depend: [parentnode_parameter1_*]

This might wait for all jobs using parameter1 to finish and start only one job.

Thanks

Research direction

Start by tracing how the depends syntax is parsed and how inbound edges are evaluated. Define how parameter-based subsets such as parentnode_parameter1_* should be selected, how completion is determined, and what behavior marks the feature as done.
