| | # Statistics for HuggingFaceFW/finepdfs-edu (Dutch (Latin script)) |
| |
|
| | Aggregate statistics computed using Polars streaming on the [HuggingFaceFW/finepdfs-edu](https://huggingface.co/datasets/HuggingFaceFW/finepdfs-edu) dataset. |
| |
|
| | ## Performance |
| |
|
| | Processed **847,361 documents** in **125.88 seconds**. |

| | | Global stats | 34.19s | |
| | | Language stats | 31.81s | |
| | | Extractor stats | 29.46s | |
| | | Dump stats | 30.42s | |
| | | **Total** | **125.88s** | |
| |
|
| | > Speed comes from Polars only reading metadata columns (not the `text` column), |
| | > thanks to Parquet's columnar format and lazy evaluation. |

|
| | ## How This Was Generated |
| |
|
| | This dataset demonstrates **Polars streaming aggregation** with HuggingFace Hub integration. |
| | Thanks to [polars#25521](https://github.com/pola-rs/polars/pull/25521), `scan_parquet` |
| | with `hf://` paths now uses far fewer API calls (139 → 1 for finepdfs-edu). |
| |
|
| | ```bash |
| | uv run polars-hf-stats.py --lang nld_Latn --output-repo davanstrien/finepdfs-nld-stats |
| | ``` |
