Key Value Stores

Key Value Stores are a type of NoSQL database that store data as a collection of key-value pairs, where each key is unique and maps to a value. They are designed for high-performance, scalable read and write operations, often used in distributed systems. The value can be simple data types like strings or numbers, or complex objects like JSON documents.

Also known as: Key-Value Databases, KV Stores, Key-Value Pairs, KV DB, NoSQL Key-Value

Why learn Key Value Stores?

Developers should use Key Value Stores when they need fast, low-latency access to data with simple query patterns, such as caching, session storage, or user profiles. They are ideal for applications requiring high throughput and horizontal scalability, like real-time analytics or gaming leaderboards, where relational databases might be too slow or complex.
