How to batch sub-graph calls

[vermapratyush]

Hi,
I am writing a multi-agent system, with the following agents (simplified version):
The sub-agent processes a file and an objective function, and returns a list of snippets.

class SubAgentState(BaseModel):
  file: str
  objective: str
  snippet: list[str]

def generate_sub_agent():
  state = StateGraph(SubAgentState)
  ....
  return state.compile()

The parent class has a list of files and a list of objective. It need to execute SubAgent on each of the file (with it's equivalent objective, based on index).

class ParentAgentState(BaseModel):
  files: list[str]
  objective: list[str]
  snippet: list[list[str]]

def generate_agent():
  state = StateGraph(ParentAgentState)
  state.add_node("subagent", generate_sub_agent())
  ....
  return state.compile()

With state.add_node("subagent", generate_sub_agent()), I am able to fuse the 2 graphs into one. How do I process all the files in ParentAgentState.files in parallel?

Is send an appropriate API to use here?

Send API seems to work fine.
