Description

Willingness to contribute

No. I cannot contribute a bug fix at this time.

Feature Request Proposal

Feathr UI should show UDF information in the lineage graph. Currently it's not showed.

Motivation

What is the use case for this feature?

Showing the UDF info could be helpful for end users to know how the input is transformed.

Details

No response

What component(s) does this bug affect?

  • Python Feathr Client: This is the client users use to interact with most of our API. Mostly written in Python.
  • Computation Engine: The computation engine that execute the actual feature join and generation work. Mostly in Scala and Spark.
  • Feature Registry API Layer: The storage layer supports SQL, Purview(Atlas). The API layer is in Python(FAST API)
  • Feature Registry Web UI layer: The Web UI for feature registry. Written in React with a few UI frameworks.

Research direction
Start by examining the Feathr UI codebase, specifically the React components for lineage graph in the Feature Registry Web UI layer. Look for where the graph data is fetched and rendered, and trace back to the Python FastAPI endpoint that serves lineage data. UDF info might be missing from the API response or not captured in the graph model. Investigate the computation engine (Scala/Spark) to see if UDF metadata is recorded, and then modify the API and UI to include it.
