The Database Cache
The Database Cache of Mimer SQL (sometimes also called the Bufferpool) ensures that large parts of the database can be kept in main memory, reducing the number of disk I/O operations needed. The size of the Database Cache can easily be changed, making it possible to effectively utilize available main memory.
The Database Cache is partitioned, which means that each partition can be viewed as an independent memory area. Since there are in effect a number of Database Caches, tasks executing simultaneously on separate CPUs have a reduced risk of conflicting when accessing a partition and so inter-processor cache coherency traffic is reduced.
