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
# or start in release mode
cargo run --release
Otherwise, 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, to-be-released).
We plan to release a stable version of RisingLight in the near future, as well as a tutorial in Chinese on how to build an OLAP database from scratch. See the pinned Roadmap issue for more information.
RisingLight is under the Apache 2.0 license. See the LICENSE file for details.
