Abstract: A column set server adapts to data use patterns by data consumers by modifying how a table produced by a data producer is partitioned into separate column sets to reduce the waste incurred in accessing the data by multiple consumers of the data. For example, the column set server adjusts a column set distribution when a new consumer process is added, when one is retired, or when relative data set size ratios change.

Abstract: A distributed storage system maintains multiple logically independent file systems. Each file system includes a data set stored by a distributed storage of the distributed storage system. During operation, access pattern levels for the multiple logically independent file systems are determined. Thereafter, the data sets included in the multiple logically independent file systems are redistributed across multiple storage devices of the distributed storage. In one aspect, redistribution of a particular data set is based at least in part on the particular file system including the particular data set and on the determined access pattern levels for the multiple logically independent file systems. In one implementation, redistribution is performed according to a uniform redistribution scheme. In another implementation, redistribution is performed according to a proportional distribution scheme.

Abstract: A method and a network that enable a computer to select a set of printer driver settings for a particular printing application are disclosed. The computer stores sets of printer driver settings in advance. Each set of printer driver settings is tagged with a label that illustrates a general aspect of this set of printer driver settings, and a list of these labels has been created by the computer. When a user fires a printing application, the user makes a selection from the list of these labels first. In response, the computer searches the stored sets of printer driver settings for a conforming set according to the selected label. The conforming set of printer driver settings will be retrieved, either from the memory unit of the computer or from another computer via the network, and used as current printer driver settings for the printing application.
