Show HN: A SQL engine with semantic operators to query unstructured data

https://github.com/robintiman/semcast

I built it using Apache Datafusion. It adds semantic operators to SQL such as MEANS which can be used to filter data by its meaning. The core idea is that a user should be able to process unstructured data while semcast takes care of optimizing the query, including LLM calls.

Would love some feedback
