Abstract
Resources are loaded into a resource container in an in-memory database system in which pages are loaded into memory and having associated physical disk storage. Each resource is assigned a new time stamp when such resource is loaded into the resource container. At least some of the references are subsequently accessed and time stamps associated with these accesses resources are selectively updated based on the type of access. These time stamps are later used to evict least recently used resources (as indicated by their time stamps) from the resource container.
