Oh how interesting, there are related database projects built on the same foundation library/tech called Data Substrate. - EloqSQL - MySQL-compatible, high performance, elastic, distributed SQL database https://github.com/eloqdata/eloqsql - EloqKV - Redis/Valkey Compatible Distributed Transactional Key-Value Store https://github.com/eloqdata/eloqkv

TiKV is a great project and we have a lot of respect for their work. EloqKV is based on a very different architecture [1], and we also have MySQL compatible [2] and MongoDB compatible [3] databases build on top of the same architecture. They all inherit the extreme performance, scalability, fault tolerance, and ACID properties due to the common underpinning.

The reason is because we use a layer (our main innovation) called DataSubstrate to build modular databases that support distributed transactions [1]. Because we use some MariaDB code (GPLv2) and some MongoDB code (AGPLv3) in our other projects [2] [3], so we license our DataSubstrate code to be compatible with both, and therefore, we also license EloqKV under both licenses.
