Agent systems break down when simple workflows evolve into tangled 30+ node graphs with unclear dependencies and sequential bottlenecks. In this episode, we explore how to scale LangGraph architectures through strategic parallelization, modular subgraphs, and dynamic task distribution. You’ll learn:

* When to use parallel execution vs. sequential flows and how to manage concurrent state updates with reducers?

* How to structure multi-agent systems using subgraphs with either shared or isolated states?

* When dynamic map-reduce patterns outperform static parallelization for variable workloads
