Zusammenfassung: | Data elements are stored at a plurality of nodes. Each data element is a member data element of one of a plurality of layouts. Each layout indicates a unique subset of nodes. All member data elements of the layout are stored on each node in the unique subset of nodes. A stored dependency list includes every layout that has member data elements. The dependency list is used to determine availability of data elements based on ability to access data from nodes from the plurality of nodes. |
