The suggested contacts and calendar events can be searchable as if they were manually entered by the user, and the user can choose to add or ignore the suggested contacts and calendar events.

Abstract: An apparatus for optimizing a skewed join is described herein. The apparatus includes logic, at least partially including hardware logic, to determine that a dataset for the skewed join comprises a skewed key that does not fit in memory. The apparatus also includes logic to model the skewed join as a queue. The apparatus also includes logic to estimate a cost of the skewed join based on the modeled queue. The apparatus evaluates different join techniques, and partitioning strategies for the skewed join, and chooses the plan with the lowest cost.

Abstract: In some examples, a computing device determines a data manipulation from a job specification. The device determines a corresponding data-processing instruction using data-source metadata, and determines and executes a corresponding query. In some examples, a device receives search keys. The device searches data-source metadata using the search keys. The device weights a first data source based on producer-consumer relationships between data sources, and ranks the first data source using the weight. In some examples, a device determines structural and content information of a data record. The device determines a data-source identifier from the structural information and stores the content information with the data-source identifier in a database. In some examples, via a user interface, a device receives a job specification and annotation data. The device stores the spec and the annotation data in a metadata repository.

Abstract: A journal optimizer in a computer database system with an adaptive journal mechanism. The adaptive journal mechanism dynamically adjusts adaptive parameters of the journal optimizer to optimize the journal based on one or more journal conditions to more efficiently utilize system resources. The adaptive parameters used to adapt the optimization include aggressiveness parameters and the location of the optimizer, where the aggressiveness parameters specify the intensity of optimization of the journal by the journal optimizer. For example, the adaptive journal mechanism may dynamically adjust an adaptive parameter of the optimizer to increase optimization of the journal when the resource utilization indicates the resources are underutilized and decrease optimization of the journal when the resource utilization indicates resources are strained.

Abstract: Adjusting system actions based on an absence of relationship acceptance may include detecting absence of connection acceptance by one or more first users in a computer-implemented social networking system. Patterns of the absence of connection acceptance of the one or more first users may be correlated. Users with common patterns of absence of connection acceptance may be clustered into a cluster of users. Absence of connection acceptance by a second user may be detected. Responsive to determining that a pattern of the absence of connection acceptance associated with the second user matches with the common patterns, a profile associated with the second user may be updated according to a template profile associated with the cluster. System actions of the social networking system may be activated for the second user based on the profile updated according to the template profile.

Abstract: Disclosed herein are system, method, and computer program product embodiments for providing read queries latch-free access to an index page. In an embodiment, a processor receives a request from a read query to access one or more records of an index page. The index page includes an update pointer and a slot array. The processor locates one or more updates prepended to the index page by locating a most recently prepended update indicated by the update pointer. Then, the processor generates a local offset table with entries in the slot array and the located one or more updates. The generated local offset table enables the processor to provide the read query access to the one or more records of the index page.

Abstract: A method includes receiving a query identifying a first entity associated with the online social network. The method then includes accessing a deep-link index of the online social network including a plurality of records of indexed deep-links to a plurality of third-party applications. A deep link to the third-party application may include instructions for accessing a display state of the third-party application associated with the entity. The method further includes identifying one or more records of the deep-link index having an entity-identifier matching the identified first entity of the query, and sending one or more search results responsive to the query. The search results may include deep links corresponding to one or more of the identified records, and each deep link may be selectable by the first user to access a display state of a third-party application associated with the first entity of the query.

Abstract: A method of providing a retargeting search service includes storing a log about query information input from a user during a preset period of time, and providing a retargeting keyword and a retargeting search result to at least one of a user mobile terminal and a user computer terminal according to an information providing point in time based on the stored log.

Abstract: Example embodiments relate to asset browsing and restoration over a network using on demand staging. A method may include accessing, by a storage access system, a first portion of a compound asset in a storage system and restoring it as a staged asset in a staging area of the storage access system. The accessing and restoring of the first portion may be performed on demand in response to an indication from a client device to browse a portion of the compound asset. The method may further include accessing the internal structure of the staged asset to generate an asset directory. The asset directory may indicate discrete items within the compound asset. The method may further include providing the asset directory to the client device over a network, and receiving an indication from the client device of at least one of the discrete items to restore to the client device.
