Demonstration shows DuckDB Python client ingesting varied file formats, integrating with Pandas/Ibis/Polars, and using the spatial extension to build a persisted cafe-finder from Melbourne’s open API. It processes a 5.6M-row CSV for sampling in ~2s and an aggregated month-by-month query in 0.1s for aggregation, exposes a lazy relationship object for delayed execution, reads 72,000 JSON files in one liner, performs S3 range scans and writes Parquet/CSV outputs, and all examples complete successfully.
