Can I use this skill to handle large datasets?

Yes, the skill provides patterns for using LazyFrames and streaming mode, which allow Polars to process datasets larger than your available RAM efficiently.

What file formats does this Polars skill support?

It provides comprehensive guidance for high-performance reading and writing of CSV, Parquet, JSON, and Excel files, as well as database connectors.

What makes Polars different from pandas?

Polars is built on Apache Arrow and uses lazy evaluation with a query optimizer, providing significantly faster performance and better memory efficiency than pandas by parallelizing operations.

Does this skill help with migrating existing code?

Absolutely. It includes specific mappings between pandas and Polars syntax, helping you translate common operations like filtering, grouping, and window functions.
