I could understand users may not want the DAG to fail outright if the branching section is not critical path like with some feature engineering use cases I've seen. It may be more intuitive to not have to create an empty branch to simply continue with the pipeline if an output doesn't need to be tracked. Could this be a configurable mode: fail or skip if no branches found? -- This is an automated message from the Apache Git Service.
