Abstract: A system and method can support federation replication in a distributed computing environment. The system can provide one or more federation replication channels between a plurality of members in a first cluster and a plurality of members in a second cluster. Furthermore, a replication request can be transmitted from a federation coordinator to the plurality of members in the first cluster, wherein each said member in the first cluster owns a set of partitions. Then, the aggregated data for each said partition in the first cluster can be sent to the plurality of members in the second cluster via said one or more federation replication channels. Additionally, using the second cluster, the system can take a persistent snapshot of information on the plurality of members in the first cluster while the first cluster is operational.

Abstract: Parallel processing files on a distributed file system, responds to a request to process the file, by partitioning the file into a set of predetermined sized blocks by a single coordinator and assigns blocks to a reader in a set of readers. Block assignments are recorded to a control table accessible to all readers. The set of readers search the control table for a row assigned to a respective reader. Responsive to locating the row, the respective reader changes a state of the row to in progress updating an associated timestamp. The respective reader scans the control table for an available set of the blocks, when all blocks currently assigned are exhausted and dynamically re-assigns an available block from another owning reader to itself and changes ownership to itself. When no rows are available, the respective reader completes processing and returns an end of file indication to the single coordinator.

Abstract: A computing system is described that identifies, based on search histories associated with a group of computing devices for a particular context, a task performed by users of the group of computing devices for the particular context. The computing system determines a first degree of likelihood of the task being performed by the users of the group of computing devices for the particular context and determines a second degree of likelihood of the task being performed by the users of the group of computing devices for a broader context that includes the particular context and at least one other context. Responsive to determining that the first degree of likelihood exceeds the second degree of likelihood by a threshold amount, and that a current context of a particular computing device corresponds to the particular context, the computing system transmits, to the particular computing device, information for completing the task for the particular context.

The method also includes identifying one or more objects, where each identified object matches at least one of the identified physical-proximity phrases having a confidence score greater than a threshold confidence score and sending to the first user one or more search results corresponding to one or more of the identified objects, respectively.

Abstract: A deduplication service can be provided to a storage domain from a services framework that expands and contracts to both meet service demand and to conform to resource management of a compute domain. The deduplication service maintains a fingerprint database and reference count data in compute domain resources, but persists these into the storage domain for use in the case of a failure or interruption of the deduplication service in the compute domain. The deduplication service responds to service requests from the storage domain with indications of paths in a user namespace and whether or not a piece of data had a fingerprint match in the fingerprint database. The indication of a match guides the storage domain to either store the piece of data into the storage backend or to reference another piece of data. The deduplication service uses the fingerprints to define paths for corresponding pieces of data.

Abstract: The disclosed system and method acquire and store performance measurements relating to performance of a component in an information technology (IT) environment and log data produced by the IT environment, in association with corresponding time stamps.

Abstract: Data mining operations are performed within a columnar database management system. The columnar database management system stores input sets of data for a data mining operation. An input set of data is represented as a column of data in the columnar database management system. The columnar database management system stores instructions to perform one or more data mining operations for processing the input sets of data. The columnar database management system receives requests for performing data mining operations and performs the processing of the data mining operation within the columnar database management system. As a result, the processing of data mining operations is performed without requiring multiple data transfers between an application implementing the data mining operations and the columnar database management system.

Abstract: A virtual assistant receives natural language interpretation hypotheses for user queries, determines entities and attributes from the interpretations, and requests data from appropriate data sources. A cost function estimates the cost of each data source request. Cost functions include factors such as contract pricing, access latency, and data quality. Based on the estimated cost, the virtual assistant sends requests to a plurality of data sources, each of which might be able to provide data necessary to answer the user query. By including user credits in the cost function, the virtual assistant provides better quality of results and answer latency for paying users. The virtual assistant minimizes latency by answering using data from the first responding data source or provides a latency guarantee by answering with the most accurate data received by a deadline. The virtual assistant measures data source response latency and caches responses for expensive requests.

Abstract: An information management system according to certain aspects uses backup copies or other secondary copies of production data for the purposes of replicating production data to another client. The secondary copies can be deduplicated copies. By utilizing available secondary copies of the data for replication, the system can reduce the impact on the production machines associated with replication. Utilizing deduplicated copies not only reduces the amount of stored data, but also reduces the amount of data that is communicated between the source and the destination, increasing the speed of the replication process.
