What if Jev spoke Arrow?

TypeSafe's new model Jev turns natural language into typed decisions, but its API only returns JSON. Columnar Technologies built Jevaro, a proxy that batches requests and returns Apache Arrow, achieving 464 states per second and costing $0.20 for 30,000 answers. They argue a native Arrow endpoint would eliminate the JSON tax and unlock probabilistic pipelines.
Jev is a new primitive, and nobody yet knows the full scope of what it will make possible.

While Jev is fast, using it is hardly bottleknecked by deserializing from JSON.
Using arrow is cool, but grpc seems like a more natural fit than arrow IPC and would give you the same benefits.
