This is really cool, not sure how I missed it. I assume catalog support will be added fairly quickly. But ironically I think the biggest barrier to adoption will be the lack of an off-ramp to a FOSS solution that companies can self-host. Obviously Polars itself is FOSS, but it understandably seems like there's no way to self-host a backend to point a `pc.ComputeContext` to. That will be an especially tough selling point for companies that are already on Spark. I wonder how much they'll focus on startups vs. trying to get bigger companies to switch, and whether they'll try a Spark compatibility layer like DataFusion (https://github.com/apache/datafusion-comet).
