The TiKV distributed transactional key-value database is now an incubating project at the CNCF (Cloud Native Computing Foundation). TiKV is a distributed database that's similar to Google Spanner and HBase but claims to be easier to use. TiKV offers georeplication, horizontal scalability and consistent distributed transactions.
TiKV can also be deployed on Kubernetes with an operator to ease installation, upgrades and maintenance. TiKV is written in the Rust programming language and implements the Radt consensus protocol.
PingCap, the company behind TiKV, also offer TiDB, a MySQL compatible layer on top of TiKV.
