摘要： A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module that is configured to perform various operations. The computing device monitors for condition(s) that triggers expansion of a private DSN memory that stores encoded data slices (EDSs), and when that condition occurs, the computing device generates a modified copy of the EDSs that includes a read and/or write threshold number of EDSs of the EDSs. The computing device transmits the modified copy of EDSs to a public DSN memory for storage within the public DSN memory. The computing device then services first read request and/or write request based on the private DSN memory that stores the plurality of EDSs and services second read request and/or write request based on public DSN memory that stores the modified copy of the plurality of EDSs.

摘要： A system and method for adaptive data placement in a distributed file system is provided. Upon creation of a new subdirectory, a first heuristic procedure is formed to determine whether the newly created subdirectory should be created locally or on a remote flexible volume. Should it be determination be made to create or store the subdirectory on a remote flexible volume, a second heuristic procedure determines which of a plurality of flexible volumes should store the newly created subdirectory.

摘要： Embodiments of the present invention disclose a method, a computer program product, and a computer system for suspending and activating a database index. A computer determines a quantity of changes for a number of rows of a database that are to be made by an update of the database. The computer determines whether to suspend an index of the database based, at least in part, on a comparison between the quantity of changes and a pre-determined threshold value. The computer suspends the index of the database based on a result of the comparison that indicates the quantity of changes at least meet the pre-determined threshold value. A suspension of the index of the database initiates a rebuilding of the index.

摘要： Several systems and methods for accessing files stored in a storage device are disclosed. In an embodiment, the method includes accessing a file allocation table (FAT) in a computer file system associated with the storage device. The FAT includes a plurality of cluster addresses corresponding to a plurality of clusters allocated to a file stored in the storage device. A cluster address is read to identify a location of a next cluster. One or more bits in the cluster address are read to determine a presence of a signature value indicating allocation of a set of contiguous clusters from among the plurality of clusters. A number of contiguous clusters is computed based on a pre-determined number of consecutive cluster addresses succeeding the cluster address if the signature value is present. The set of contiguous clusters are read from the storage device based on the computed number of contiguous clusters.

In one embodiment, for example, a system for instant indexing includes a token store storing sets of tokens for current versions of documents. The system further includes a tokenizer server configured to tokenize new versions of the documents and to generate sets of tokens for the new versions of the documents, an instant indexer configured to determine tokens to use to index the documents based on identified differences between the sets of tokens for the new versions of the documents and the sets of tokens for the current versions of the documents, and to generate index mutations including the tokens to use to index the documents, an index mutation journal configured to store the generated index mutations in association with timestamps, and an index mutation server configured to provide, to index servers, from the index mutation journal, generated index mutations for the index servers that are associated with timestamps that are newer than specified timestamps.

摘要： Embodiments are directed towards a system and method for a cloud-based front end that may abstract and enable access to the underlying cloud-hosted elements and objects that may be part of a multi-tenant application, such as a search application. Search objects may be employed to access indexed objects. An amount of indexed data accessible to a user may be based on an index storage limit selected by the user, such that data that exceeds the index storage limit may continue to be indexed. Also, one or more projects can be elastically scaled for a user to provide resources that may meet the specific needs of each project.

摘要： A method for distributing tables to a cluster of nodes managed by database management system (DBMS), is disclosed. Multiple data placement schemes are evaluated based on a query workload set to select a data placement scheme for the cluster of nodes. Tables, used in join operations in the workload set, are selected for evaluation of data placement schemes. Query execution costs for the workload set are generated based on estimating a query execution cost for each data placement scheme for the tables. The data placement scheme that has least costly estimated execution cost for the workload set is selected as the data placement scheme for the cluster of nodes managed by DBMS.

摘要： A method for providing a link in an electronic file being presented to a user which includes defining a customized viewpoint for the user. The viewpoint includes a preference for the user that provides an association between a data pattern and a computer network resource. The method also includes generating a request for content, receiving an electronic file in response to the request, and evaluating the electronic file to recognize a match between at least one portion of the electronic file and the data pattern. Upon recognizing a match, the electronic file is modified to include a link to the computer network resource associated with the matching data pattern, and the modified electronic file is presented to the user. Thus, the link included in the electronic file presented to the user is customized for the user, and different users who retrieve the same content can be provided with links to different computer network resources depending on their respective viewpoints.

摘要： Some implementations may include a gateway module to receive, from a software application, a command to perform an action to a database. The gateway module may translate the command to create a translated command based on configuration data associated with the database. The configuration data may enable the gateway module to determine how to perform the action to the database. The gateway module may determine whether the translated command is valid based on the configuration data. If the translated command is valid, the gateway module may send the translated command to the database. The gateway module may receive a result of performing the translated command from the database. The gateway module may determine, based on the translated command, the result, or both, whether conditions associated with a triggered command are satisfied (e.g., met). If the conditions are satisfied, the gateway module may send the triggered command to the gateway module.
