Abstract: Techniques for processing queries are provided. In one approach, an execution plan for a query includes multiple sub-plans, one or more of which are selected at runtime while one or more other sub-plans are not executed during execution of the execution plan. In another approach, data about misestimate is generated and stored persistently for subsequent queries. In another approach, statistics for a database object are generated automatically and efficiently while the database object is created or data items are added thereto. In another approach, a hybrid histogram is created that includes a feature of frequency histograms and a feature of height-balanced histograms. In another approach, computer jobs are executed in such a way to avoid deadlock. In another approach, changes to a database object trigger a hard parse of a query even though an execution plan already exists for the query.

Abstract: An efficient data deduplication method for use in a dispersed storage network (DSN). After a data object is received for storage in the DSN, it is determined whether a substantially identical data object has previously been encrypted and stored. The determination may be made, for example, by comparing an encryption key reference value relating to the data object to key reference information stored in DSN memory. If not detected, the data object is encrypted using an encryption key based on the data object. The encrypted data object is then compressed and stored. The encryption key and a key reference value are also stored as encoded key slices in DSN memory. If the data object was previously stored, it is encrypted using a retrieved encryption key that is substantially identical to the data object. The data object may then be compressed for storage using a pattern based data compression function.

Abstract: Systems and methods for displaying graphical database query results on a map by dynamically selecting graphical query result display modes are described. In one example, the system includes a distributed database query system having a remote server and a local client computer. The remote server receives a query request from the client and obtains a threshold number of results for display. If a particular query provides less than the threshold number of results, the system uses a first interactive graphical query result mode utilizing client rendering. If the query provides the threshold number of results or more, the system uses a second non-interactive graphical query result mode utilizing server rendering.

Abstract: An apparatus comprises a network interface and a processor communicatively coupled to the network interface. The network interface communicates with a database comprising a plurality of columns and a plurality of views. Each view is associated with at least one column of the plurality of columns. The processor receives a request to determine one or more noncompliant views of the database. For each view and each column associated with the view, the processor determines whether the column is associated with a privacy indicator that indicates that the column should be masked and whether the view masks the column. The processor then determines that the view is noncompliant if the view does not mask at least one column that should be masked, and generates a report that indicates whether each view of the database is noncompliant. The network interface communicates the report.

Each search-result module includes references to one or more of the identified objects matching the query command corresponding to the search-result module. The method also includes scoring the search-result modules; and sending each search-result module having a score greater than a threshold score to the first user for display.

Abstract: Data connections from a remote login session are identified and an identification query may be transmitted by the remote login session to endpoints (e.g., servers) of the data connections. In response to the identification query, identification information may be received from the endpoints. Furthermore, the identification information may be compared with a local identification of a local server that hosts the remote login session. A file created by the remote login session may be stored at an endpoint over a data connection where the local identification matches a portion or all of the identification information of the endpoint of the data connection.

Abstract: At least one read operation of at least one object of a data container is initiated. The data container includes an anchor object, a first internal data object and a first garbage collection object, the anchor object comprising a pointer to a versioned structure tree. Thereafter, in response to the at least one incompatible write operation, a second internal data object and a second garbage collection object are created for the data container. The second garbage collection object has a reference to the second internal data object. Subsequently, the second internal data object is installed in the anchor object and the first garbage collection object is passed to a garbage collection process so that space used by the first garbage collection object in a database can be reused. Related apparatus, systems, techniques and articles are also described.

Abstract: Systems and methods are disclosed herein for performing classification of documents or performing other tasks based on rules. A rule generator receives a request for a rule that will receive as an input a document and output an outcome such as a classification of the document, addition of the document to a whitelist or blacklist, or occurrence of some other outcome. The rules are applied to a document and the document and outcome of the rules are presented to a rater. A rating of the accuracy of the outcome is received from the rater and the rating is propagated to quality metrics of rules that contributed to the outcome. Rules with a quality metric above a threshold may be added to a production rule set. Rules with a quality metric below a threshold may be removed.
