In Memory Databases: Speed at Your Fingertips In memory databases store data in RAM rather than on disk. This design bypasses much of the slow disk I/O, so reads and writes happen in microseconds. The speed boost makes these systems a good fit for tasks that need immediate results. Yet RAM is volatile and memory capacity is limited, so you should plan for durability and growth. Common use cases Real-time analytics and dashboards Session stores and fast caching Leaderboards and live gaming state Price ticks and monitoring data How they work Most in-memory databases keep hot data in memory and offer fast data structures for quick access. They can run with different interfaces, from simple key-value styles to SQL-like queries. Some systems run mostly in memory but periodically write changes to disk, forming a hybrid model that balances speed with durability. ...
