In-Memory Storage
In-memory storage is a data storage approach where information is kept in the main random-access memory (RAM) of a computer rather than on traditional disk-based storage systems. This enables extremely fast data access and processing speeds, as RAM operations are orders of magnitude quicker than disk I/O. It is commonly used for caching, session management, real-time analytics, and high-performance applications.
Developers should use in-memory storage when building applications that require low-latency data access, such as real-time trading platforms, gaming leaderboards, or high-traffic web session management. It is particularly valuable for read-heavy workloads where data can be pre-loaded into memory, and for scenarios where temporary data persistence (like user sessions) needs fast retrieval without the overhead of disk operations.
