NewSQL databases provide scalable performance similar to that of NoSQL systems combining the ACID properties of a traditional database management system. VoltDB, NuoDB, Clustrix, MemSQL, and TokuDB are some of the examples of NewSQL database.

NewSQL databases are distributed in nature, horizontally scalable, fault tolerant, and support relational data model with three layers: the administrative layer, transactional layer, and storage layer. NewSQL database is highly scalable and operates in shared nothing architecture. NewSQL has SQL compliant syntax and uses relational data model for storage. Since it supports SQL compliant syntax, transition from RDBMS to the highly scalable system is made easy.

The applications targeting these NewSQL systems are those that execute the same queries repeatedly with different inputs and have a large number of transactions. Some of the commercial products of NewSQL databases are briefed below.
