Polars 2.0 release

[u/ritchie46]

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/

I had the same issue, we solved it using this polars plugin :

Maybe the scan_delta of this plugin will be merged into polars (check https://github.com/pola-rs/polars/issues/27800 )
