What is NewSQL?

NewSQL (pronounced new ess-cue-ell or new sequel) is a relational database management system (RDMS) that aims to provide NoSQL system scalability while also maintaining the consistency of a traditional database system.

NewSQL combines ACID (atomicity, consistency, isolation and durability) compliance with horizontal scaling for online transaction processing workloads. Enterprise systems that handle data, such as financial and order processing systems, are too big for a traditional relational database. At the same time, these enterprise systems aren’t practical for NoSQL systems because they have transactional and consistency requirements. NewSQL provides the scale and reliability without requiring more infrastructure or development expenditures.

NewSQL uses SQL to ingest new information, execute transaction processing at a large scale, and change the contents of the database. The main categories of NewSQL include new architectures, transparent sharding middleware, SQL engines and database as a service (DBaaS).
