What is In-Memory?
In contrast to databases that store data on disk or SSDs, In-Memory databases are designed to rely on computer memory for data storage. By removing the need to access drives, in-memory data is intended to provide the fastest response times possible. Even so, in-memory databases run the risk of losing data in the event of a process or server failure because all data is kept solely in the main memory. For applications like gaming leaderboards, session storage, and real-time analytics that need microsecond response times or see high traffic spikes, in-memory databases are the best choice.
