Abstract: Various embodiments describe multi-site cluster-based data intake and query systems, including cloud-based data intake and query systems. Using a hybrid search system that includes cloud-based data intake and query systems working in concert with so-called “on-premises” data intake and query systems can promote the scalability of search functionality. In addition, the hybrid search system can enable data isolation in a manner in which sensitive data is maintained “on premises” and information or data that is not sensitive can be moved to the cloud-based system. Further, the cloud-based system can enable efficient leveraging of data that may already exist in the cloud.

Abstract: One or more client threads are executed. One or more processing threads corresponding to the one or more client threads are executed. The processing threads are configurable to generate statistical information for each database query statement processed by the corresponding client thread. The statistical information is generated from the processing threads. The statistical information is stored in chunks of memory managed via a plurality of queues. The chunks of memory containing the statistics are analyzed. Outlier statements are filtered based on the statistics. Non-outlier statements are stored by a storage device.

Abstract: Methods and systems to sample event messages are described. As event messages are generated by one or more sources, the event messages are stored in a storage queue. An event message policy that represents conditions for storing event messages in a sample log file are input. For each event message output from the storage queue, the event message may be stored in a sample log file when one or more of the conditions of the event message policy are satisfied. The event messages of the sample log file may be displayed in a graphical user interface that enables a user to change the event message policy.

Abstract: A complex data type is encoded over columns of a table of a columnar database by mapping fields of the complex data type to the columns. An optimized query can be generated for a query specifying the complex data type. The optimized query specifies the columns to which the fields specified within the query are mapped, instead of specifying the fields. The optimized query can be processed against the database in a late materialization manner to fulfill the query.

Abstract: Described herein is a system and method for multiplexer tree (muxtree) indexing. Muxtree indexing performs hashing and row reduction in parallel by use of each select bit only once in a particular path of the muxtree. The muxtree indexing generates a different final index as compared to conventional hashed indexing but still results in a fair hash, where all table entries get used with equal distribution with uniformly random selects.

Abstract: Techniques for ascribing social attributes to content items and for selecting content to display in a content feed are described. According to various embodiments, accessing one or more content items accessible via a network are accessed, each of the content items having received one or more social activity signals. Thereafter, members of an online social network service that submitted the social activity signals may be identified. Member profile data identifying member profile attributes of the members cemented the social activity signals may then be accessed. Thereafter, social attribute information may be generated and associated with each of the content items, the social attribute information identifying the member profile attributes of the members that submitted the social activity signals associated with each of the content items.

Abstract: Monitoring statements in a database environment. Substantially all database query statements to be executed against a database in the database environment are analyzed to determine if a statement has an outlier statistic. Database queries that do not have an associated outlier statistic are serviced. Further analysis is performed for statements having an outlier statistic to determine if the corresponding statement poses a security risk to the database environment.

Abstract: An indexing system indexes data entries in a database and processes queries of the database. The indexing system generates a key database storing keys that each represent a vector of a relative attribute between two data entries. For instance, a temporal distance indicates a relative time between timestamps of events represented by the two data entries. In other embodiments, relative attributes may be based on physical proximity, altitude, semantics, etc. The indexing system may also generate a key space database to enable efficient lookup of events associated with a target entity for indexing new data entries. For example, the indexing system may perform one read operation using the key space database to lookup all events associated with the target entity. Furthermore, the indexing system may determine responses for queries to retrieve events that occurred within a target temporal distance before or after a target type of event.

Abstract: Data structures and applications are defined with the point-and-click visual tools or speech recognition and recorded as metadata descriptions, which are converted at runtime to generate underlying software code (e.g., C #, SQL, JavaScript, etc.) to implement the application. The data structures include application data elements described in a data serialization format, such as JSON, are stored in a NoSQL database. Each application data element includes fields that each represent an individual value. Each field is defined with a label, a data type, and attributes. The data structures also describe relationships or links between application data elements, as well as data-driven or time-based rules that drive further data manipulation and interactions within and external to the programming development environment through a variety of interfaces (e.g. HTTP, SMTP, SMS).

Abstract: A system and method for providing an improved user interface for executing data operations. The method includes: identifying a first node and a second node, wherein the first node is selected from a first connections graph and the second node is selected from a second connections graph, wherein each node is associated with a user account having a plurality of attributes, wherein the first and second nodes share at least one common attribute; generating an influence indicator for each of the first node and the second node; identifying a data operation executed by the first node on a dataset when the influence indicator of the first node is higher than the influence indicator of the second node, wherein the identified data operation is not executed by the second node; and sending, to a device of the second node, a notification indicating the identified data operation.

Abstract: Systems, methods, and computer-executable instructions for parallel searching in program synthesis. A task to synthesize in a domain specific language (DSL) is received. The task is synthesized. Synthesizing the task includes generating sub-goals based on the task. The synthesized task includes a subset of the sub-goals. An estimated completion time for each of the sub-goals is expressed using the DSL is determined. The sub-goals are scheduled based on the estimated completion time. Some of the sub-goals are scheduled to be executed in parallel. The sub-goals are solved based on the scheduling to synthesize the task in the DSL. An elapsed real time to complete the synthesizing the task is reduced compared to scheduling the sub-goals in an order based on sub-goal generation.
