NewSQL
NewSQL is a class of modern relational database management systems that aim to provide the scalability of NoSQL databases while maintaining the ACID (Atomicity, Consistency, Isolation, Durability) guarantees and SQL query capabilities of traditional SQL databases. These systems are designed to handle high-volume, distributed workloads with strong consistency and transactional support, often using innovative architectures like in-memory processing or distributed consensus protocols.
Developers should learn and use NewSQL databases when building applications that require both horizontal scalability for large datasets and high transaction rates, along with strict data consistency and complex SQL queries, such as in financial systems, e-commerce platforms, or real-time analytics. It bridges the gap between traditional SQL databases, which can be limited in scalability, and NoSQL databases, which often sacrifice consistency or query flexibility.
