DuckDB: Zero-Setup SQL Analytics for Local Data Processing

DuckDB fills the critical gap between lightweight tools like Pandas and heavyweight databases like PostgreSQL, enabling developers to perform fast SQL analytics on CSV and Parquet files without server setup. Its columnar architecture and in-memory processing deliver database-level performance for local analysis, while flexible persistent modes ensure data durability when needed. This makes rapid data exploration and analytics prototyping accessible to Python developers without infrastructure overhead.
