NewSQL first emerged in the early 2010s. It represents a type of relational database designed to provide the scalability and performance of NoSQL databases while maintaining ACID compliance as traditional, monolithic SQL databases. These databases are typically more complex to set up and manage and can be more expensive than SQL databases.

NewSQL databases were engineered as a relational SQL database system but with a distributed architecture. This does not mean  they are the same as distributed SQL. Even though both were designed to evolve transactional databases, there are significant differences in the capabilities and the value they bring to a company.

Popular examples of NewSQL databases include ClustrixDB, Vitess, Citus, VoltDB, and NuoDB.
