## The Hook

Polars is what pandas would be if designed today.

## What's Good

The API is expressive: method chaining, lazy queries, and automatic parallelization. Memory efficiency is dramatically better than pandas for large datasets. The query optimizer makes naive code fast.

## The Catch

Different API than pandas—existing codebases need rewriting. The ecosystem is smaller; some pandas integrations do not exist.

## Verdict

What pandas would be if designed today.
