We (Splitgraph) implemented WASM UDFs in Seafowl [0], a database written in Rust based on Datafusion and optimized for executing queries "at the edge" and returning cache-friendly HTTP responses. Users can call CREATE FUNCTION within an SQL query to create a WASM UDF (docs [1]).

We blogged [2] about this feature, and you can read the relevant PRs [3] containing the changes necessary for its implementation.

Sure thing! And no worries, we haven't been great at marketing ourselves :)
