Key-value store

A key-value store is a type of database that stores data as pairs: a unique identifier called a "key" and the associated information called a "value." Think of it like a digital dictionary where each word (key) maps to a definition (value). This setup allows for fast and efficient retrieval of data because you can quickly find the information by searching for its key. Key-value stores are commonly used in applications needing quick access to large amounts of data, such as caching, session management, and real-time analytics.
