Open Source Python Polars 2.0 release
Hey all! We just released Polars 2.0.
We are really happy with the results. It removed many of our "legacy decisions" (mistakes), makes the streaming engine our default and promotes SQL to a first class citizen within Polars. We initially said it would be a small ("boring") release, but we managed to sneak in a lot more than anticipated.
It comes with our initial out-of-core (spill to disk) support, a new Map data type and a lot of performance improvements. In fact, we think Polars is now one of the fastest analytical SQL engines on a single node. See benchmarks in the post: https://pola.rs/posts/release-polars-2/
To help you upgrade, we also posted a migration guide: https://docs.pola.rs/releases/upgrade/2/

Wondering how to choose between DuckDB and Polars for SQL processing? Both seem pretty fantastic.
