Rust Data Processing with Polars: CSV, Parquet, Joins, and Lazy Queries

A practical two-hour session on Rust Data Processing with Polars, focused on CSV, Parquet, Joins, and Lazy Queries. Rust is used as the implementation context while the core lesson stays on software engineering fundamentals, reliability, testing, and operational clarity.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Rust Data Processing with Polars
• Apply CSV in a small working example
• Apply Parquet in a small working example
• Apply Joins in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
