Ktema: The Machine Answers

Editorial interest 82/100 Selection signal · not a rating of the site

Ktema is an embedded storage engine for answering multi-axis, spatiotemporal queries on devices without an operating system or conventional database.

Landing page captured for the 2026-09-16 issue.

Field notes

Ktema uses a coordinate composed of origin, event, and time as an address, replacing an explicitly maintained multi-axis index with address computation. The homepage reports a 4,309-byte live heap peak for a bare-metal RISC-V write/read round trip and a 0.93-millisecond three-axis query across 100,000 records. It presents the implementation as a Rust library with a C interface, with links to documentation and GitHub.
