Use in-memory database to optimize server performance [199cloud-Ina]

In fact, an in-memory database is a database that operates directly in memory. Compared with disk, the data read and write speed of memory is several orders of magnitude higher, and storing data in memory can greatly improve the performance of applications compared to accessing from disk. The in-memory database abandons the traditional way of disk data management, redesigns the architecture based on all the data in memory, and makes corresponding improvements in data cache, fast algorithm and parallel operation. therefore, the data processing speed is much faster than that of the traditional database.

But the problem of security can be said to be the biggest injury to the in-memory database. Because the memory itself has the natural defect of power loss, when we use the in-memory database, we usually need to take some protection mechanisms for the data in the memory in advance, such as backup, logging, hot backup or clustering, synchronizing with disk database and so on. For some data that is of low importance but want to respond to user requests quickly, you can consider memory database to store, and at the same time, you can solidify the data to disk on a regular basis.
