Why NoSQL is highly scalable?

Horizontal Scaling - The real advantage of NoSQL is horizontal scaling, aka sharding. Considering NoSQL 'documents' are sort of a 'self-contained' object, objects can be on different servers without worrying about joining rows from multiple servers, as is the case with the relational model.

Why are NoSQL databases better?

NoSQL databases don't require any predefined schema, allowing you to work more freely with “unstructured data.” Relational databases are vertically scalable, but usually more expensive, whereas the horizontal scaling nature of NoSQL databases is more cost-efficient.

Which database is most scalable?

Apache Cassandra is the most established scalable massive database. It an Open source NoSQL key-value database that provides low latency, it is fault tolerant(using replicas), scalable and decentralized; meaning it does not follow a master-slave pattern to provide high availability.

Why is MongoDB scalable?
