An Implementation Guide to Building a DuckDB-Python Analytics Pipeline with SQL, DataFrames, Parquet, UDFs, and Performance Profiling
In this tutorial, we build a comprehensive, hands-on understanding of DuckDB-Python by working through its features directly in code on Colab. We start with the fundamentals of connection management and data generation, then move into real analytical workflows, including querying Pandas, Polars, and Arrow objects without manual loading, transforming results across multiple formats, and writing expressive SQL for window functions, pivots, macros, recursive CTEs, and joins. As we progress, we also explore performance-oriented capabilities such as bulk insertion, profiling, partitioned storage, multi-threaded access, remote file querying, and efficient export patterns, so we not only learn what DuckDB can do, but also how to use it as a serious analytical engine within Python.
