An in-memory database (IMDB) stores and manages data exclusively in the main memory (RAM) instead of a traditional disk.
It is ideal for high-speed data processing applications, such as real-time analytics platforms, financial trading systems, and online transaction processing (OLTP) systems.
Benefits of In-memory Database
- Concurrency: In-memory databases enable concurrent data access and manipulation by multiple users without affecting performance.
- Data storage and processing: Since IMDB stores data in the system’s RAM, read and write operations are extremely fast with minimal latency.
- Reduced disk I/O overhead: Since IMBD doesn’t use disk storage, it significantly reduces disk I/O overhead, enhancing the entire system’s performance.
- Data protection: Because RAM is temporary memory, IMDB protects against data damage or loss by regularly copying data to disk.
