Category:In-Memory Databases

From Big Database List

In-Memory databases retain data in a servers memory and minimize disk writes. The primary purpose of this type of database is to improve performance over disk based databases. Due to the volatile nature of Random Access Memory, this type of database is most suited to high read / low write databases, or databases which are completely re-creatable from an alternative disk based database (i.e. an In-Memory Cache).

Some In-Memory databases do use disk for persisting recovery logs.
