RisingLight is an OLAP database system for educational purpose. It is still in rapid development, and should not be used in production.

Currently, RisingLight only supports Linux or macOS. If you are familiar with the Rust programming language, you can start an interactive shell with:

cargo run           # start in debug mode
cargo run --release # or start in release mode

If you meet with any build issues, see Install, Run, and Develop RisingLight for more information. We provide step-by-step guide on how to compile and run RisingLight from scratch.

After successfully building RisingLight, you may import some data and run SQL queries. See Running TPC-H Queries.

All documentation can be found in docs folder.

At the same time, dev docs are also available in make docs (latest) or crates.io (stable).

The RisingLight project was initiated by a group of college students who have special interests in developing database systems using modern programming technologies. The project is generously sponsored by RisingWave Labs, a startup innovating the next-generation database systems. RisingWave Labs is hiring top talents globally to build a cloud-native streaming database from scratch. If interested, please send your CV to hr at risingwave-labs.com .
