摘要： It is provided a method, comprising associating value ranges to each of a predefined number of fields, wherein the value ranges for each of the fields are continuous; associating, for each of the fields, bijectively rowkey field values to the value ranges of the respective field, wherein the rowkey field values for each of the fields are continuous; generating rowkeys, wherein each rowkey comprises one of the rowkey field values for each of the fields, and wherein a rowkey is generated for each of the corresponding combinations of the rowkey field values; wherein the associating of the rowkey field values is further adapted to associate the rowkey field values such that for each of the fields and for each of the rowkeys: a first rowkey field value for the respective field of the respective rowkey is neighbored to a second rowkey field value for the respective field of a second rowkey of the rowkeys, and a first value range of the respective field of the respective rowkey is continuous with a second value range of the respective field of the second rowkey, wherein the rowkey field values of the respective field comprise the first and second rowkey field values, and the value ranges of the respective field comprise the first and second value ranges.
