Axiom: Composable Query Engines Built on Velox
· 8 min read
Introduction
Axiom is a C++ library for building fully composable, high-performance query engines, built on top of Velox. Think of it as Lego for query processing — the pieces are compatible, but don't restrict how you put them together. Configure each layer, swap in your own components.
Today, users face significant friction moving between interactive queries, batch processing, streaming, and AI training data preparation — different engines, different semantics, different quirks. With Axiom, we can build all of these on a shared foundation, delivering consistent semantics across deployment modes.
