LangGraph Parallel Branches Concurrency

[jamesheavey]

Hi all,

I have made a graph using parallel branches with map reduce, following this: https://langchain-ai.github.io/langgraph/how-tos/map-reduce

Graph works as expected, however, I want to limit the concurrency of the parallel branches in line with the rate limit of my LLM saas api provider.

Is there a nice way to achieve this?
