Rayforce

Embeddable columnar analytics and graph traversal engine in pure C17.

Rayforce combines morsel-driven vectorized execution, a multi-pass query optimizer, and a native CSR graph engine in a single pipeline. It is queried through the Rayfall language, exposes a C API for embedding, and targets Linux, macOS, and Windows.

Quick Start Functions Reference

At a glance

  • Pure C17, zero external dependencies. Single binary, single shared library, single header.
  • Columnar with morsels. Vectorized execution over fixed-size morsels; SIMD where possible.
  • Multi-pass optimizer. Predicate pushdown, join reordering, accelerator-index selection.
  • Graph engine. Native CSR storage, PageRank, Dijkstra, betweenness, Louvain, MST.
  • Datalog. Recursive rules over EAV triples.
  • Rayfall language. Lisp-flavoured functional surface; full table-and-graph combinator vocabulary.
  • IPC. Client/server with auth, restricted mode, and connection-lifecycle hooks.
