Summary
StreamProcessor.visualize()throughStreamProcessorWorkflowso callers don't need to reach through private attributesvisualize_workflows(instrument)utility that iterates all registered workflow specs, instantiates each with default params, and collects graphviz diagrams from those backed by aStreamProcessorMotivation
ess.reduce.streaming.StreamProcessorhas avisualize()method that produces color-coded dependency graphs showing dynamic keys, accumulators, static nodes, and targets. This was not accessible through our wrapper layers. Having a utility to auto-generate these for all registered workflows is useful for documentation and could later be wired into the dashboard UI (e.g., backend renders SVG, displayed viapn.pane.SVGon demand).Test plan
