Abstract
When receiving a predetermined command regarding an assigned key to a node apparatus, a history element is registered, which includes a first Logical Clock Value (LCV) at a first time the predetermined command was received, and a data value at a second time represented by the first LCV. When receiving a reference request to reference a data value at a third time represented by a specific LCV, a first marker is registered, which includes, as the specific LCV, a second LCV at a time when the reference request was received or a third LCV designated by the reference request, and further includes information concerning the reference request. When a fixed LCV in a system becomes not less than the specific LCV, a data value corresponding to the assigned key at the third time is identified from the history elements including first LCVs that are not greater than the specific LCV.
