Suggestion: reference WFGY Problem Map (RAG / LLM debugging checklist) for Modin users

Author: onestardaoCreated Feb 21, 2026Updated Feb 21, 2026

Hi Modin team,

thank you for making it easier to scale pandas-style workloads. I see Modin being used more and more in pipelines where people prepare large corpora, logs, and features that eventually feed into vector stores and LLM / RAG systems.

I maintain an MIT-licensed project called WFGY Problem Map, which is a 16-question checklist for debugging real-world RAG / LLM pipelines. It focuses on data and retrieval failure modes that appear when you move from a notebook prototype to a production system.

Why this could matter for Modin users:

  • Modin is often used when the volume of documents or events is large enough that mistakes in preprocessing become very expensive to debug later.
  • Several of the 16 failure modes describe exactly these “worked on a sample, broke at scale” issues once an LLM and retriever are added.
  • The checklist is framework-agnostic and can be used no matter which backend Modin is running on.

External references for WFGY Problem Map include:

  • Harvard MIMS Lab ToolUniverse
  • QCRI LLM Lab Multimodal RAG Survey
  • Rankify (University of Innsbruck)

Suggestion:

If you think this is useful for your community, one option would be a small “Further reading” link in the docs for users who are combining Modin with vector stores and LLMs:

“RAG / LLM debugging checklist: WFGY Problem Map (16 failure modes)”

Thank you for your time and for all your work on Modin.

Best,
