Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing conversion path performance measures and reports. In one aspect, user interaction data are obtained, were the user interaction data specify user interactions for a plurality of conversions. User interactions that are associated with each conversion are selected from the user interaction data, where the associated user interactions for each conversion are user interactions with a converting user during the conversion cycle for the conversion. Using the user interaction data for the selected user interactions, a quantity of user interactions that are associated with each conversion and occurred during the conversion cycle for the conversion are determined. In turn, conversion path performance measures are computed and reports specifying the conversion path performance measures are generated.

Abstract: Techniques are disclosed relating to determining a predicted time interval for querying a database beginning at a starting point in time to retrieve a specified number of records. A computer system receives a request for records from a database that stores timestamped records, where the request is for a specified number of records beginning at a starting point in time. The computer system then determines a predicted time interval for querying the database beginning at the starting point in time to retrieve the specified number of records, where the predicted time interval may be determined by a machine learning module that is trained using historical database transaction data. Such techniques may advantageously improve the efficiency of individual queries in fetching a desired amount of data from a database for applications.

Abstract: Disclosed is a system and method for analyzing, by a server computer, closed captioning text associated with a media program being experienced by a user having a client device. The server computer obtains, based on the analyzing, a subject matter of a portion of the media program from the closed captioning text. The server computer constructs a query associated with the determined subject matter and submits the query to a computer network as a search query. The server computer receives, in response to the submitting of the query, content relating to the subject matter and measures an elapsed time period between the receiving of the content and the obtaining of the subject matter. If the elapsed time period is less than a predetermined period of time, the server computer communicates, to the client device, information related to the content.

Abstract: Techniques are disclosed relating to providing and using probabilistic data structures to at least reduce requests between database nodes. In various embodiments, a first database node processes a database transaction that involves writing a set of database records to an in-memory cache of the first database node. As part of processing the database transaction, the first database node may insert, in a set of probabilistic data structures, a set of database keys that correspond to the set of database records. The first database node may send, to a second database node, the set of probabilistic data structures to enable the second database node to determine whether to request, from the first database node, a database record associated with a database key.

Abstract: Tagging application resources for snapshot capability-aware discovery is described. If an application's host determines that one of an application's resource satisfies any snapshot capability rule, the application's host associates the application resource with a snapshot capable tag. The application's host outputs an identifier of the application resource and any associated snapshot capable tag to a backup server. The application's host inputs a request from the backup server to create a snapshot of the application resource associated with the snapshot capable tag and creates the snapshot of the application resource associated with the snapshot capable tag.

Abstract: Described herein is a computer implemented method. A change event record of a change history dataset is processed by determining if the change event record matches any field matching records. The change event record matches a particular field matching record if it is determined that a change event record field identifier matches a field identifier of the particular field matching record and a new value associated with the change event record matches a comparison variable of the particular field matching record. In response to determining that the change event record matches a single field matching record, the change event record is associated with a unique field identifier of the single field matching record in a data store.

Abstract: A method comprises receiving a request to restore a given snapshot of a plurality of snapshots from a cloud storage platform to a storage array. In the method, a first metadata file corresponding to the given snapshot is downloaded from the cloud storage platform, and data corresponding to the given snapshot is written to the storage array. An additional metadata file corresponding to a previous snapshot of the plurality of snapshots with respect to the given snapshot is downloaded. The first metadata file and the additional metadata file are compared to determine whether one or more offsets in the additional metadata file are present in the first metadata file. Data corresponding to any of the one or more offsets determined to be absent from the first metadata file is written to the storage array, and the one or more absent offsets are added to the first metadata file.

Abstract: Techniques of transaction support for a database are disclosed herein. One example technique includes generating a new version value for key-value pairs in the database and creating, in the database, a new key-value pair corresponding to a parameter to be updated with a new value using both the generated new version value and a name of the parameter as a key and the new value as the corresponding value for the created new key-value pair. The example technique can then include determining whether creating the new key-value pair is completed successfully in the database, and in response to determining that creating the new key-value pair corresponding to the parameter is not completed successfully, the existing value of the parameter is returned as a current value of the parameter instead of the new value in response to a query for the current value of the parameter.

Abstract: A request to restore an instance of an object that is stored in a storage associated with a cluster of nodes to a target destination is received. Data of the object is divided into a plurality of data portions. Corresponding data portions of the plurality of data portions are assigned to each node of a plurality of nodes of the cluster. It is determined that a first node of the cluster of nodes does not currently store in a storage associated with the first node at least a part of a corresponding data portion of the object assigned to the first node. At least the part of the corresponding data portion of the object assigned to the first node is received at the first node from a second node of the cluster of nodes. At least the part of the corresponding data portion of the object received from the second node is provided from the first node to the target destination.

After each module performs its respective process, it generates a report, and when all modules have completed the processor transmits to the individual a response based on the produced reports, e.g. as a webpage.

Abstract: A global and local row count limit associated with a limit query are received by a stop operator of a first execution node among a set of execution nodes that are assigned to process the limit query. Local distributed row count data is generated based on a local row count corresponding to a number of rows output by the first execution node in processing the query. Based on determining the local row count satisfies the local limit, the first execution node buffers rows produced in processing the query. The local distributed row count data is updated based on remote distributed row count data received from a second execution node. A stopping condition is detected based on determining the global limit is satisfied based on updated local distributed row count data and query processing by the first execution node based on detecting the stopping condition.
