# DuckDB datasets for `id` querying on FineWeb |
|
|
|
|
|
This repo contains DuckDB databases to check whether a given WARC UID exists in a FineWeb dump. Usage example |
|
|
is given below, but note especially that if you are using URNs (likely, if you are working with CommonCrawl data), |
|
|
then you first have to extract the UID (the `id` column is of type `UUID` in the databases). |

## Usage |
|
|
|
|
|
Originally developed to be used with a library to look for Creative Commons licensing information: https://github.com/BramVanroy/CommonCrawl-CreativeCommons/ |
|
|
|
|
|
```python |
|
|
import re |
|
|
import duckdb |
|
|
|
|
|
|
|
|
uid_re = re.compile(r"<urn:uuid:([a-zA-Z0-9]{8}-?[a-zA-Z0-9]{4}-?[a-zA-Z0-9]{4}-?[a-zA-Z0-9]{4}-?[a-zA-Z0-9]{12})>") |
|
|
|
|
|
duckdb_path = "duckdbs/fineweb/fw-CC-MAIN-2019-30.duckdb" |
|
|
con = duckdb.connect(duckdb_path, read_only=True) |
|
|
|
|
|
uuid_urn = "<urn:uuid:93081b76-bc46-4d2f-98f0-2d9687b80967>" |
|
|
# !! Important: extract the UUID from the URN |
|
|
uid = uid_re.sub("\\1", uuid_urn).replace("-", "") |
|
|
|
|
|
query = "SELECT EXISTS (SELECT 1 FROM data WHERE id = ?)" |
|
|
exists = bool(con.execute(query, uid).fetchone()[0]) |
|
|
|
|
|
print(f"Does ID {uid} exist? {exists}") |
|
|
# Does ID 93081b76bc464d2f98f0-2d9687b80967 exist? True |
|
|
``` |
