# 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**.

| Step | Time |
|------|------|
| 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
```
