KantoDB

The product is an open source OLTP-oriented hybrid SQL database that provides transactional SQL storage and querying. It addresses the need for a relational database that can run embedded as a programming library or as a standalone server. It is for software developers, data teams, and operations/IT teams in business environments building data-backed applications. It is positioned directly against Postgres and SQLite and is implemented in Rust using DataFusion and Arrow for data handling with RocksDB for storage.
