Abstract: A memory system includes a non-volatile memory in which data is stored in a plurality of pages including a first page and a second page and a memory controller. The controller is configured to perform a first write operation on the first page at a first time, perform a second write operation on the second page at a second time after the first time, perform a first read operation on the first page at a time after the first time using a first parameter and store a first index value in association with the first page and the first parameter, and determine a second parameter for a second read operation to be performed on the second page using a time difference between the first time and the second time and the first index value stored in association with the first page.

Abstract: A performance measurement indexing system indexes a data store containing data entries indicative of message processing by an application. The application includes a plurality of checkpoints, and the data store contains data logged upon each message traversing the checkpoints in the application. The performance measurement indexing system determines which data entries relate to messages that satisfy a delay condition, and limits queries run on the data store to those data entries, thereby increasing the speed and efficiency with which queries can be serviced.

Abstract: A method, a computer program product, and a computer system handle a data gap in sequential data. The method includes receiving the sequential data for a period of time. The method includes selecting the data gap in the sequential data at a timestamp. The method includes determining a sliding window associated with the data gap based on the timestamp for a duration of time. The sliding window includes dependent data from which the data gap depends. The method includes, as a result of the dependent data of the sliding window including at least one window data gap, generating extracted patterns based on the dependent data to mask the at least one window data gap. The method includes determining a prediction to fill the data gap using a prediction model that takes as input modified data based on the dependent data and the extracted patterns.

Abstract: In one embodiment, a data reconciliation engine works with data store nodes included in a distributed data store system to ensure consistency between the data store nodes. In operation, the data reconciliation receives a different data snapshot from each of the data store nodes. In response, the data reconciliation engine generates one or more recommendations designed to resolve inconsistencies between the data snapshots. The data reconciliation engine then transmits each recommendation to a different data store node. Because the data reconciliation engine performs many of the resource-intensive operations included in the data reconciliation process, the resources of the data store nodes may focus primarily on processing client requests instead of performing data reconciliation operations. Consequently, unlike conventional data store node based reconciliation applications, the data reconciliation engine may process large volumes of data without unacceptably increasing the time required for the distributed data store system to respond to client requests.

Abstract: Systems and methods are disclosed for processing and executing queries against one or more dataset. As part of processing the query, the system determines whether the query is susceptible to a significantly imbalanced partition. In the event, the query is susceptible to an imbalanced partition, the system monitors the query and determines whether to perform a multi-partitioning determination to avoid a significantly imbalanced partition.

Abstract: A method includes receiving, by a first computing device of a distributed file system from a second computing device, a first timestamp associated with a first version of a set of objects stored on the second computing device, the first timestamp corresponding to a modification time of the first version of the set of objects, or a first transfer time of the first version of the set of objects from at least one of the first computing device or a third computing device of the distributed file system to the second computing device. The method also includes identifying a second version of the set of objects stored on the first computing device, the second version of the set of objects having a second timestamp, the second timestamp corresponding to a modification time of the second version of the set of objects or a second transfer time. The method further includes transferring the second version of the set of objects to the second computing device to be stored on the second computing device.

Abstract: A system writes to a replicated direct access storage device (DASD) a record of each step within a job as each step begins and as each step completes. The records are maintained on the replicated DASD for a predetermined period of time. The predetermined period of time is, for example, the greatest amount of lag in replication of all storage systems operating within the system. The records are stored, for example, in an open jobs and datasets (OJD) file, where the file itself is a dataset. The dataset is written to by an online task (e.g., OJDSTC) which gathers input from two sources. Upon job completion, the records are stored, for example, in an OJD journal and removed from the OJD file.

Abstract: Methods and devices for recovering data may include receiving an identification of at least one file on the computer device impacted by a cyber threat. The methods and devices may include receiving a last known good time stamp for the at least one file that identifies a point in time prior to the cyber threat. The methods and devices may also include transmitting, to a remote backup provider associated with the at least one file, a restore request to restore the at least one file with restored content based at least on the last known good time stamp. The methods and devices may include receiving, from the remote backup provider, a restored file with the restored content.

Abstract: In one embodiment, a metric collection system may collect application metrics across multiple data centers in specific time intervals. A local collection point 108 may establish an absolute reference time for a local data center 102. The local collection point 108 may determine a source reporting interval for an application 106 based on the absolute reference time. The local collection point 108 may receive a source metric report 300 for the application 106 based on the source reporting interval.
