6. FAQ
What is NewSQL?
NewSQL refers to a class of modern relational databases that provide the scalability of NoSQL systems while retaining the ACID guarantees and SQL interfaces of traditional databases.
How does NewSQL differ from NoSQL?
NewSQL databases offer strong consistency and transactional support, whereas NoSQL databases often prioritize availability and partition tolerance, sometimes sacrificing consistency.
Are NewSQL databases suitable for all applications?
NewSQL databases are ideal for applications requiring high transaction rates and strong consistency, but may not be necessary for use cases that can tolerate eventual consistency.
