Daily Term: In-Memory Database

In-Memory Database

An In-Memory Database stores data in RAM instead of on disk, enabling extremely fast read and write operations. For example, Redis is often used as an in-memory database for caching or real-time analytics. In-memory databases are ideal for applications requiring low latency, such as gaming leaderboards or session stores, but they are limited by memory size and can lose data on crashes unless paired with persistence mechanisms.
