    Abstract: Techniques are disclosed relating to the execution of a set of program instructions in the background. A parent environment of an application executing on a computer system may receive a request from a first child environment within the parent environment to execute a set of program instructions. The first child environment does not permit the set of program instructions to be executed within the first child environment while the application is backgrounded. In response to the request, the parent environment may spawn a second child environment within the parent environment that permits the set of program instructions to be executed while the application is backgrounded. The parent environment may cause the set of program instructions to be executed within the second child environment and may return a result of the executing to the first child environment.

    Abstract: Techniques are disclosed relating to processing data stored within database tables in a parallelized manner. In various embodiments, a computer system maintains a database having a database table storing data for a plurality of tenants and an index structure storing indexes for accessing data stored in the database table. In some embodiments, the computer system receives, from a particular tenant, a request to perform a task that includes operating on particular data. In some embodiments, the computer system determines a portion of the index structure corresponding to the particular tenant and divides a range of indexes within that portion into a plurality of index sub-ranges. In various embodiments, the computer system processes portions of the task in parallel by determining an index sub-range for each of a plurality of threads and causing each of the threads to operate on a portion of the particular data specified by its index sub-range.

    Abstract: Embodiments regard maintaining data consistency between transactional and non-transactional data stores. Embodiments may include receiving a request to archive a set of data stored in a first data store, recording a high water mark in the first data store for the set of data, and archiving the set of data. Archiving the set of data may include copying the set of data into a second data store and inserting a high water mark for the set of data in the first data store and the second data store. Embodiments may further include updating a reference high water mark upon successful completion of operations for the archiving of the data, the reference high water mark representing completion of a last successful archive operation, and, upon receiving a query for requested data contained in the first or second data store, determining whether to allow viewing of the requested data based at least in part on a current value of the reference high water mark.

    Abstract: A client device receives search queries and displays via a user interface, search results representing a set of the records based on the search queries. The client device monitors implicit user interactions with search query terms and records displayed in response to various search queries, for example, implicit user interactions representing movements of cursor on the portion of user interface displaying a particular record. The client device receives a partial search query. Partial search results representing a set of the records based on the partial search query are determined for display via the user interface. The relevance score for each record is determined based on implicit user interactions associated with past search queries. The partial search results are ranked based on the relevance scores and displayed by the client device according to the ranked order.

    Abstract: Systems and techniques are disclosed relating to management of a database. A method may include maintaining, by a computer system, a multi-tenant database operable to store a plurality of objects. Each object may be capable of including up to a maximum potential number of definable fields. Each field may have an associated index number that has been assigned sequentially. The method may include receiving user-defined data values for a subset of the maximum potential number of fields of a particular object, and storing, for the particular object, a boundary value indicating a range of index values that have been defined for the particular object. The method may further include, in response to determining that the particular object has been accessed, selectively processing a number of fields of the particular object. The number of fields may be determined based on the stored boundary value for the particular object.

    Abstract: An agent for navigating a mobile automated system is disclosed herein. The navigation agent receives a navigation instruction and visual information for one or more observed images. The navigation agent is provided or equipped with self-awareness, which provides or supports the following abilities: identifying which direction to go or proceed by determining the part of the instruction that corresponds to the observed images (visual grounding), and identifying which part of the instruction has been completed or ongoing and which part is potentially needed for the next action selection (textual grounding). In some embodiments, the navigation agent applies regularization to ensures that the grounded instruction can correctly be used to estimate the progress made towards the navigation goal (progress monitoring).
