The collection of qualities to which NewSQL systems for online transaction processing are measured against are Autonomy, Consistency, Independence, and Durability.
While the collection of qualities you mentioned – Autonomy, Consistency, Independence, and Durability – are important aspects to consider in database systems, they do not specifically represent the characteristics by which NewSQL systems for online transaction processing are typically measured. The qualities you mentioned seem to be a combination of different concepts related to database management.
In the context of NewSQL systems, the focus is on providing scalable and high-performance databases that combine the benefits of traditional SQL databases with the scalability and distributed capabilities of NoSQL databases. Some of the key characteristics and measurements of NewSQL systems for online transaction processing include:
Scalability: NewSQL systems aim to handle large-scale workloads by providing horizontal scalability, allowing for the distribution of data and processing across multiple nodes or servers. This scalability enables efficient handling of high-volume transactional workloads.
Performance: NewSQL systems strive to deliver high-performance processing of online transactions. They typically optimize query execution, indexing mechanisms, and data caching strategies to minimize response times and ensure efficient transaction processing.
ACID Compliance: ACID (Atomicity, Consistency, Isolation, Durability) compliance is a fundamental requirement for transactional databases. NewSQL systems maintain strong consistency and durability, ensuring that transactions are executed reliably and in a controlled manner.
SQL Compatibility: NewSQL systems provide SQL compatibility, allowing businesses to leverage their existing SQL skills and applications. This compatibility enables a smooth transition from traditional SQL databases to NewSQL systems while retaining the benefits of SQL-based querying and data manipulation.
Distributed Architecture: NewSQL systems are designed to distribute data across multiple nodes or servers, ensuring fault tolerance, high availability, and data redundancy. This distributed architecture allows for horizontal scaling and efficient handling of concurrent transactions.
Transactional Support: NewSQL systems support ACID transactions across distributed environments, allowing for consistency and reliability in multi-node configurations. This capability ensures that transactions can be executed with data integrity even in highly distributed systems.
While Autonomy, Consistency, Independence, and Durability are important aspects of database systems, they do not specifically represent the key characteristics by which NewSQL systems for online transaction processing are typically measured. The mentioned qualities may be more applicable to general database management concepts or different types of databases.
