Best practices for parallel nodes (fanouts)

Hi @rkauf as for me, I go by these rules: Understand the execution model (super-steps) LangGraph executes in discrete super-steps; nodes that are scheduled together run in parallel, then the system synchronizes before the next step. This is inspired by Pregel’s message-passing model. Use Send for dynamic fan-out, Command for update+route For map-reduce/orchestrator-worker patterns, return a list of Send(node, arg) to dynamically spawn workers. Use Command(update=..., goto=...) when yo…
