What is a key-value NoSQL database, and what are its use cases?
Krishnapriya Rajeev
26-Apr-2023A key-value NoSQL database is a type of NoSQL database that stores data as key-value pairs. In a key-value database, each data record is identified by a unique key, which is used to retrieve the data associated with that key. This value can be any type of data, such as a string, number, or even binary data.
These types of databases are commonly used for caching frequently accessed data. By storing data in memory, key-value databases can provide fast access to frequently accessed data and reduce the load on backend systems. Similarly, they can also be used to store session data for web applications, which can easily be stored and retrieved using a key-value database, and the data automatically removed after a certain period of time.
Another common use case of key-value databases is to store user profile information. Each user profile can be stored as a key-value pair, and the data easily be retrieved and updated as needed.

26-Apr-2023A key-value NoSQL database is a type of NoSQL database that stores data as a collection of key-value pairs. Each key-value pair consists of a unique key and its associated value. The key is used to retrieve the value from the database, and the value can be any type of data, including strings, numbers, objects, or arrays.
Key-value databases are designed for high performance, scalability, and fault-tolerance. They are simple to use and provide fast access to data, making them ideal for use cases such as:
Some examples of key-value NoSQL databases include Redis, Memcached, Riak, and Amazon DynamoDB.
