Key-Value Store
A key-value store is a type of NoSQL database that stores data as a collection of key-value pairs, where each key is unique and maps to a value. It is designed for high-performance read and write operations, often used in scenarios requiring low-latency data access. Key-value stores typically support simple operations like get, put, and delete, making them efficient for caching, session storage, and real-time applications.
Developers should learn and use key-value stores when building applications that require fast data retrieval, such as caching layers to reduce database load, session management in web applications, or real-time systems like gaming leaderboards. They are ideal for use cases where data is accessed by a unique identifier and does not require complex queries or relationships, offering scalability and simplicity compared to traditional relational databases.
