Spice.ai

In plain words

Spice Cayenne is a lightweight, open-source data and AI engine built in Rust that accelerates SQL queries, hybrid search, and LLM inference across distributed storage systems. It uses Apache DataFusion and Ballista to materialize data from multiple sources into embedded databases like SQLite and DuckDB. The latest version introduces a new Data Accelerator based on Vortex, a columnar format designed for faster random access, scanning, and writes compared to Parquet. It is used by enterprises including Barracuda Networks and Twilio.
