Tags: mojo, exasol, udf, database, zmq, protobuf

Score: 6.5/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 4)

A Script Language Container (SLC) for Exasol written entirely in Mojo, implementing the ZMQ+protobuf UDF protocol from scratch with no Rust/C++ host. It enables native Mojo UDFs inside the database with Python interop, offering compiled speed for CPU-bound hot paths. Experimental but technically ambitious.

Target audience: data engineers and backend developers working with Exasol
