Patent number: 10977280Abstract: Systems and methods for optimizing memory in an interest-driven business intelligence system in accordance with embodiments of the invention are illustrated. A dictionary for storing values of a dataset may be partitioned in accordance with some embodiments. The partitions of the dictionary may be generated by mapping and reducer processes. The mapping processes receive a value, determine the dimension of the data to which the value belongs, and provides the value to a reducer process that handles the determined dimension. Each reducer process generates partitions of the dictionary for each dimension. The number of values in each partition is determined and compared to a threshold value. Partitions that have a number of values greater than the threshold are stored in a common memory. Partitions smaller than the threshold value can be combined with other partitions such that the cardinality of the combined partition exceeds the threshold value.Type: GrantFiled: February 23, 2018Date of Patent: April 13, 2021Assignee: Workday, Inc.Inventors: Kevin Scott Beyer, Mayank Pradhan, Vignesh Sukumar

Patent number: 9170883Abstract: A network storage server includes a tool for detecting and fixing errors while the network storage server remains online (available for servicing client requests), which includes enabling a user to approve or disapprove remedial changes before the changes are committed. The technique bypasses the usual consistency point process for new or modified data blocks representing potential remedial changes. At a consistency point, dirty data blocks representing the potential remedial changes are written to a change log file residing outside the volume. The modified data blocks are written in sequential order to logical blocks of the change log file. In response to a user input indicating that a potential change should be committed, the corresponding modified data blocks are read from the change log file in the order in which they were written to the change log file, and they are written to persistent storage in that order.Type: GrantFiled: June 17, 2014Date of Patent: October 27, 2015Assignee: NetApp, Inc.Inventors: Yong Cho, Maya Palem, Vignesh Sukumar, John K. Edwards, David Grunwald, Andy Kahn

Patent number: 9019123Abstract: System and method for monitoring the health of modules in a web-based collaboration environment are disclosed. In one aspect, embodiments of the present disclosure include a system having one or more host servers configured to receive client requests, process the client requests to determine one or more data items, select one or more modules having the one or more data items stored thereon, and responsively transfer one or more queries requesting availability of the one or more modules. The system also includes one or more health monitoring servers configured to receive the one or more queries, identify the availability of the one or more modules, and send one or more responses to the one or more queries indicating the availability of the one or more modules. The one or more health monitoring servers are configured to periodically determine the availability status of the one or more modules.Type: GrantFiled: May 4, 2012Date of Patent: April 28, 2015Assignee: Box, Inc.Inventors: Antoine Boulanger, Tomas Barreto, Vignesh Sukumar, Sam Ghods

Patent number: 8843533Abstract: This disclosure presents checking file system consistency for a storage server. During a start up phase of a file system, a consistency checker, upon receiving a request from an internal client for a part of data managed by a file system of the storage server, checks file system consistency only for a part of metadata. The part of metadata is used to maintain consistency of the requested data. After the consistency check of the part of metadata is completed, the internal client is allowed to access the requested data before a remainder of the metadata is checked for consistency.Type: GrantFiled: November 12, 2008Date of Patent: September 23, 2014Assignee: NetApp, Inc.Inventors: Vignesh Sukumar, Andy Kahn
