RisingLight is an educational OLAP (online analytical processing) database system written in Rust, designed to help people learn modern database internals. It runs as an interactive SQL shell, can be used as an embedded database crate, and is explicitly not intended for production use.

Use cases

• learn how an OLAP database engine works internally
• run SQL analytics queries on local data
• study database source code as a database systems student
• use an embedded analytical database in a Rust project
• run TPC-H benchmark queries locally
• experiment with a lightweight SQL engine in Rust

When to choose

• you want a readable, educational codebase for learning or teaching database internals
• you need a small embedded OLAP engine for experimentation or research
• you want to run analytical SQL queries and TPC-H-style workloads in a simple local environment

When to avoid

• you need a production database — the project explicitly states it is not production-ready
• you require full SQL coverage, transactions, or the performance and reliability of mature databases
• you need Windows support — only Linux and macOS are currently supported
