Abstract: In a data storage and retrieval system wherein data arranged in nodes is stored and retrieved in pages, each page comprising a cluster of nodes, a method comprising: monitoring ongoing data retrieval to find retrieval patterns of nodes which are retrieved together and to identify changes in said retrieval patterns over time; and periodically reclustering the data nodes among said pages dynamically during usage of the data to reflect said changes, so that nodes more often retrieved together are migrated to cluster together and nodes more often required separately are migrated to cluster separately, thereby to keep small an overall number of page accesses of said data storage and retrieval system during data retrieval despite dynamic changes in patterns of data retrieval. The low number of page accesses allows the reclustering to be carried out concurrently with data access.
