A collection of interesting datasets and the tools to convert them into ready-to-use formats.

• curated and cleaned datasets: quality over quantity
• all tools and pipelines are streaming: first results are available immediately
• fields and units are clearly labeled and properly-typed
• data is output in immediately usable formats (Parquet, Arrow, DuckDB, SQLite)
• datasets conform to reasonable standards (UTF-8, RFC3339 dates, decimal lat/long coords, SI units)

Requires Python 3.8+.

git clone https://github.com/saulpw/readysetdata.git
cd readysetdata

Then from within the repository,

make setup

or

pip install .

or

python3 setup.py install

Output is generated for all available formats and put in the OUTPUT directory (output/ by default). Size and time estimates are for JSONL output on a small instance.

• 84k movies and 28m ratings from MovieLens

• 9m movies/tv (1m rated), 7m tv episodes, 12m people from imdb.

• 2.2m US place names and lat/long coordinates from USGS GNIS
• 13.6m non-US places from NGA GNS.

• 4m Wikipedia infoboxes organized by type, in JSONL format
• Xm article summaries (first paragraph and first sentence)

See results immediately as they accumulate in output/wp-infoboxes.

• TPC-H data generated with DuckDB)

• generated with Faker
• joinable products, customers, and orders tables for a fake business
• unicode data, including japanese and arabic names and addresses
• includes geo lat/long coords, numeric arrays, and arrays of structs

All available formats will be output by default. Specify a subset of formats by setting the FORMATS envvar, or pass -f <formats> to individual scripts. Separate multiple formats with ,.

• Apache Parquet: parquet
• Apache Arrow IPC format: arrow and arrows
• DuckDB: duckdb
• SQLite: sqlite

These live in the scripts/ directory. Some of them require the readysetdata module to be installed. For the moment, set PYTHONPATH=. and run from the toplevel directory.

Extract <filename> from .zip file at <url>, and stream to stdout. Only downloads the one file; does not need to download the entire .zip.

Download from <url> and stream to stdout. The data for e.g. https://example.com/path/to/file.csv will be cached at cache/example.com/path/to/file.csv.

Parse XML from stdin, and emit JSONL to stdout for the given <tag>.

Parse JSONL from stdin, and append each JSONL verbatim to its <field-value>.jsonl.
