NoSQL Database is a solution for applications with the following characteristics:
- Produce and consume data at high volume and velocity
- Require instantaneous response time to match user expectations
- Developed with continuously evolving data models
- Scale on–demand based on the dynamic workloads
The Key-Value datatypes running on-premise, or as a cloud service with on-demand throughput and storage based provisioning.
Sharding replication is an approach that is used for providing it with scalability. This creates a proper balance among the database systems and improves scalability.
So for question
The scalability of key-value database is achieved through which method?
The scalability of this database is achieved through sharding replication.
