Abstract: Systems and methods are provided for limiting cardinality of large datasets. A query is received from a client device. In response to the query, a query dataset comprised of a plurality of data records is retrieved from a remote data store. A fragmentation relation, representation relation, visualization relation, and result relation of the query dataset are determined. The result relation is returned to a client device. Based a selection from the result relation via graphical user interface of the client device, an inverse function is determined for mapping the selection back to the original data relation. A subset of data records corresponding to the selection are retrieved and returned to the client device for rendering in a graphical user interface.

Abstract: In one embodiment, a method receives a list of subscribers at a set interval time. Each subscriber includes one or more updates in which an update to the data stored in a database is required. A queue process in a plurality of queue processes is selected based on a first selection process where different queue processes are used over multiple set interval times. The queue process places subscribers in the list of subscribers in a plurality of queues using a placement process that is based on a characteristic of the subscribers. Also, the queue processes in the plurality of queue processes use different placement processes to place subscribers in the plurality of queues. The method then retrieves subscribers from the plurality of queues based on a second selection process, the retrieved subscribers being provided to the plurality of processors for processing of the respective updates for the subscribers.

Abstract: Innovations in the area of server-side processing when committing transactions to disk in a distributed database system can improve computational efficiency at database nodes and/or reduce network bandwidth utilization. For example, when transactions are committed in a database system, at a master node of the database system, a server uses different threads for certain processor-intensive operations and certain I/O-intensive operations. Or, as another example, when transactions are committed in a database system, at a master node of the database system, a server groups jobs for I/O requests.

Abstract: Described herein is a framework for providing and securing data access by external users. In accordance with one aspect of the framework, an external schema is generated to pair with an existing company schema in a database. The company schema may own data stored in the database. One or more access-control views that expose one or more subsets of the data may further be generated. The external schema may be granted access to the one or more access-control views. Synonyms may be created to rename access-control views, so that the synonyms share common names with corresponding database objects accessible via the company schema. External users may then access the data visible to them via the synonyms that are used to alias the access-control views.

Abstract: The disclosure generally describes computer-implemented methods, software, and systems for modeling and deploying decision services. One computer-implemented method includes operations for identifying a sequence number of a first message, the sequence number indicating a position of the first message within a first sequence of messages. If a second message positioned prior to the first message in the first sequence is in a final processing state and the second message in the first sequence is a parent message, a plurality of child messages associated with the second message are identified. Each child message is associated with a sequence number indicating a position of the child message within a second sequence associated with the plurality of child messages. The computer-implemented method determines whether a child message positioned at the end of the second sequence is in a final processing state.

The uniform customization system outputs the retrieved customization data indicating the current working context of a user, which may be used by the user to locate customization options in a customization user interface of the software application, for customizing functions performed in the current working context.

Abstract: Disclosed herein are system, method, and computer program product embodiments for minimizing table lock duration during lost change resynchronization between a source table and a replica table. An embodiment operates by detecting a restart at a source node or a replica node. A source table at the source node is then locked based on the detection. A database transaction is then created for a lost change resynchronization operation and the source table is unlocked. The database transaction is then compared to another database transaction based on its timestamp. Based on the comparison, either the database transaction for the lost change resynchronization operation or the other database transaction is executed.

Abstract: Flexible text searching for data objects can be implemented. For example, inexact matching of key name terms can be supported. An inverted index can be used to find data objects having key names with terms that are a superset of the key name term being searched. A similar index can be used for values, and the search results can be determined via an intersection. Pattern searching and other features can be supported. Text searching for schema-less collections of data objects can be supported for use in enterprise computing scenarios.

An upper layer comprises a central server node communicating with server nodes and coordinating jobs of the different platforms.

Abstract: Data use restrictions are linked with a data value for a data instance, such as in a data type implementation. The data use restrictions can be compared with a purpose associated with an operation request, such as an operation request from a software application, to determine whether the operation is permitted or prohibited. The data use restrictions can be automatically propagated to derivative data. Log entries can be generated for operations involving the data. The data use restrictions can include a data subject identifier and a data identifier, which may be used to locate related data and data associated with a particular data subject.

Abstract: Embodiments facilitate the efficient handling of service requests by a Platform-as-a-Service (PaaS) infrastructure. The platform may comprise a central controller communicating with a plurality of execution agents on one or more hosts. The central controller may parse client requests manipulating application state (e.g., scale, start, stop app, clear) into a sequence of fine-grained instance requests (e.g., start, stop, stop all, clear) that are distributed to the application program interfaces (API) of execution agents on the platform. The central controller may assign a priority to the fine-grained requests. The priority may take into consideration one or more factors including but not limited to: request creator (user, system); operation type (start, stop, stop all, clear); instance number; sequence number of the fine grained request within the original received request; hierarchy level (organization, space); and application.
