Debug Log #1 — The Pipeline That Looked Broken
The article discusses the author's experience debugging a local ETL pipeline designed for processing conversational PDFs. Initially, the pipeline appeared broken due to long execution times and lack of visible output, but further investigation revealed it was still functioning albeit slowly. The author learned to better understand the system's behavior and identified a specific schema mismatch as the root cause of the issues encountered.
- ▪The author built an ETL pipeline to process long conversational PDFs into structured datasets.
- ▪Initial debugging efforts were unsuccessful due to a lack of understanding of the system's operational behavior.
- ▪The author discovered that the pipeline was not actually broken but was slow and blocked at certain stages.

The system extracted dialogue, cleaned it, generated QA artifacts, and loaded the results into SQLite for downstream analysis. By the time this debugging process started, the core extract-transform-load flow already worked.
