Vortex is an extensible, state-of-the-art format for columnar data. It includes specifications & tools for manipulating possibly-compressed arrays in-memory, on-disk (file format), and over-the-wire (IPC format). Vortex is built around the latest research from the database community.

SpiralDB donated Vortex as a Sandbox-tier project to LF AI & Data Foundation in June 2025.
