| Exploring the BBC News subset of the FineWeb dataset (via HuggingFaceFW/fineweb's dated subsets on HF), | |
| originally a Common Crawl dataset. Iterating on a previous use of the C4 dataset [here](https://github.com/lmmx/bbcc4). | |
| ## Speed benchmarking | |
| The sample 10BT (14 files, each 2.15GB = 30.1GB, only loading 3 columns: url, text, language) | |
| - Each file takes about 45 seconds | |
| - There are ~25,000 files in the other ~100 non-sample subsets, which suggests ~13 days estimated processing time. | |

| - LazyFrame with `scan_parquet`/`sink_parquet` seems to make it marginally faster (but not tested | |
| extensively), I decided to use it regardless as it should reduce the memory load. | |
