Haystack

The Haystack integration allows you to use Component as Burr Action using the HaystackAction construct. You can visit the examples in burr/examples/haystack-integration for a notebook tutorial.

class burr.integrations.haystack.HaystackAction(

component: Component,

reads: list[str] | dict[str, str],

writes: list[str] | dict[str, str],

name: str | None = None,

bound_params: dict | None = None,

do_warm_up: bool = True,

)

Burr Action wrapping a Haystack Component.

Haystack Component is the basic block of a Haystack Pipeline. A Component is instantiated, then it receives inputs for its .run() method and returns output values.

Learn more about components here: https://docs.haystack.deepset.ai/docs/custom-components

burr.integrations.haystack.haystack_pipeline_to_burr_graph(

pipeline: Pipeline,

) → Graph

Convert a Haystack Pipeline to a Burr Graph.

NOTE. This currently doesn’t support Haystack pipelines with parallel branches. Learn more https://docs.haystack.deepset.ai/docs/pipelines#branching

From the Haystack Pipeline, we can easily retrieve transitions. For actions, we need to create HaystackAction from components and map their sockets to Burr state fields

EXPERIMENTAL: This feature is experimental and may change in the future. Changes to Haystack or Burr could impact this function. Please let us know if you encounter any issues.
