TensorBase

TensorBase was a modern big-data warehouse project written in Rust, aimed at engineers who wanted a high-performance analytical database inspired by, and aiming to be compatible with, ClickHouse. It explored several firsts in database engineering, including a no-LSM, write-and-read optimized storage layer and running on real-world RISC-V hardware.

The project reported faster write throughput and faster simple aggregation query speed than ClickHouse in its own benchmarks, alongside experiments with a 'copy-free, lock-free, async-free, dyn-free' design in its critical path and an early prototype of a whole-lifecycle JIT SQL query engine, some of which was shared only through blog posts, presentations and videos rather than released in the open-source repository.

The README states plainly that the project has paused in the general data-warehousing space, explaining that the maintainers did not want open source to become a copy-and-fork game and chose to step back rather than compete on GitHub star counts. They recommend ClickHouse for anyone seeking a production-ready data warehouse today, while TensorBase remains available for people who want to study database internals or high-performance Rust techniques. It is released under the Apache-2.0 license.
