Data Science Yes, But in Kotlin!

on YouTube ↗31m

" summary

A runnable Kotlin data-science stack is presented as an alternative to Python, combining Kotlin Notebook with Maven dependencies, DuckDB accessed via JDBC, Apache Arrow for zero-copy data transfer, Kotlin Dataframe and Candy charts. The demo loads a 9 GB DuckDB dataset (~400 million taxi rows), runs a 500-row query in ~2 s and a full aggregation in ~14 s, then performs joins (including per-week joins with weather) and plots per-quarter prices and other visualizations; code is available on GitHub and interactive joins/plots work though some tools remain under development.
