DuckDB Out-of-Core Analytics
DuckDB is an in-process columnar OLAP engine that runs vectorized SQL directly over Parquet/CSV files and Arrow tables, spilling to disk so aggregations over datasets far larger than RAM still complete. It occupies the SQLite niche for analytics: no server, one file or none, and query results that hand back to pandas or Polars zero-copy.
