Hey! Does anyone know if a query

Hey! Does anyone know if a query pipeline can take different paths or routes via an if condition or similar? Or does it have to be done on the whole set of functions?

Yea, using conditional links

Plain Text

qp.add_link(
    "a",
    "b",
    condition_fn=lambda inputs: not inputs["done"],
)

@Logan M hey! thanks for your answer! Is there any more documentation regarding this?

LLogan M

This page has a much more in-depth example
https://docs.llamaindex.ai/en/stable/examples/agent/agent_runner/agent_around_query_pipeline_with_HyDE_for_PDFs/

The example above is really all you need though tbh

@Logan M does it only work with an agent pipeline? or can you do it with a normal query pipeline (meaning, using FnComponent instead of AgentFnComponent)

LLogan M

You can do it with whatever components you want 👍

Great! Thanks

Basically it just runs the condition function using the outputs of a (i.e. the inputs of b) to see if the link should actually be followed
