NewSQLmoottorit

NewSQLmoottorit, often referred to as NewSQL databases, represent a class of modern relational database management systems designed to address the scalability challenges of traditional relational databases while maintaining ACID compliance and SQL interface. They aim to provide the best of both worlds: the transactional consistency and familiar query language of traditional SQL databases and the horizontal scalability and high availability of NoSQL systems.

These systems emerged as a response to the limitations encountered by web-scale applications that outgrew the capabilities of monolithic relational databases. Traditional scaling methods for SQL databases, such as vertical scaling (adding more power to a single server), become prohibitively expensive and have inherent limits. Horizontal scaling, distributing data across multiple machines, is a more cost-effective approach for massive datasets, but it often comes at the cost of consistency guarantees in many NoSQL solutions.

NewSQLmoottorit achieve their goals through various architectural innovations. Some employ distributed architectures that allow for automatic sharding and replication of data across a cluster of commodity hardware. They often leverage techniques like distributed transactions, optimistic concurrency control, and specialized consensus algorithms to ensure data integrity and consistency even in a distributed environment. The SQL interface is typically preserved, allowing existing applications and developers to migrate with minimal disruption. Examples of NewSQLmoottorit include Google Spanner, CockroachDB, and YugabyteDB, each with its own specific approach to distributed consensus and data management.
