# Statistics for HuggingFaceFW/finepdfs-edu (English (Latin script))

Aggregate statistics computed using Polars streaming on the [HuggingFaceFW/finepdfs-edu](https://huggingface.co/datasets/HuggingFaceFW/finepdfs-edu) dataset.

## Performance

Processed **23,023,372 documents** in **2608.95 seconds**.

| Step | Time |
|------|------|
| Global stats | 686.56s |
| Language stats | 634.40s |
| Extractor stats | 648.34s |
| Dump stats | 639.65s |
| **Total** | **2608.95s** |

> 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 finepdfs-stats.py --lang eng_Latn --output-repo davanstrien/finepdfs-eng-stats
```
