Abstract: Embodiments of the present technology relate managing database query concurrency. A method of the present technology can include receiving a query, generating a first query plan that can be used to execute the query in system memory without any system memory constraints, and estimating a system memory cost for executing the query in the system memory using the first query plan. The method can also include placing the query in a queue if available system memory does not satisfy the estimated system memory cost. The method can further include conditionally selecting the query from the queue, conditionally generating a second query plan for the query that can be used to execute the query in the system memory in compliance with a system memory constraint, and conditionally executing the query in the system memory.

Abstract: A system and method that provides a rule based randomized media content management system. The system includes a database that stores media content that is associated with category metadata that identifies content of the media content with corresponding categories. Moreover, a programming rules engine generates a list of approved media content based on business rules and a predictive rules engine generates media content selection characteristics based on media display device data and media consumption data associated with the viewer. Furthermore, a media content playlist engine is provided that generates a media content playlist by applying the generated media content selection characteristics to the list of approved media content to select media content, such that the resource consumption by the media display device is minimized by selecting media content that is targeted to the viewer of the media display device according to one or more business rules.

Abstract: A service workflow agent associated with a particular service of a provider network identifies a repository in which workflow descriptors indicative of tasks to be performed by the service are stored. In response to determining that a modification has been applied at one such repository, the agent examines a particular workflow descriptor stored in the repository. The agent initiates an attempt to implement a first task indicated in the descriptor. Subsequently, the agent updates the descriptor in accordance with an optimistic concurrency control technique to indicate a status of the first task.

The selected final answer is output as a final answer to the question via a computing device. The context based selection involves determining a context of the input question and selecting a final answer from the one or more candidate answers based on the context of the input question. The selected final answer is an answer previously provided in association with the context of the question.

Abstract: In one embodiment, a computer-implemented method includes receiving a regular expression (regex) and input data. One or more spans are identified representing one or more matches in which the regex matches at least a portion of the input data. Each span corresponds to a corresponding match and includes a start offset of the corresponding match in the input data and an end offset of the corresponding match in the input data. The one or more matches are identified in a sequence. An order of the sequence of the one or more spans is modified. One or more filtered spans are generated, by a computer processor, by filtering out a subset of the one or more spans that are each contained by at least one other span in the one or more spans. The identifying, the modifying, and the filtering are performed at streaming rate.

Abstract: The technology disclosed relates to a system that provides exactly-once processing of stream data. The system includes a queue manager which receives a stream of data. The system establishes aggregation intermediation checkpoints during processing of the received data. To do this, the system partitions delivery of the data stream at offsets, saves partition demarcation offsets at the end of processing windows, and saves intermediate aggregation results to a distributed file system with a window identifier (abbreviated ID) that correlates the offsets and the aggregation results. At each checkpoint, the intermediate aggregation results can be initially saved on at least one write-ahead log (abbreviated WAL) on the distributed file system and, post-saving, persisted to storage in accordance with a fault tolerance scheme.

Abstract: According to an aspect of the present disclosure, a query builder sends to a node in a cloud, a request for meta-data related to objects, and in response receives from the node, the meta-data specifying information related to objects exposed by the node. Upon receiving from a user a partial query and a current edit location during building of a corresponding complete query, the query builder determines, based on the received meta-data, the current edit location, and the partial query, a list of identifiers which are potential candidates for insertion at the current edit location. The query builder then displays the list of identifiers to the user, and receives a selection of an identifier from the displayed list. The query builder incorporates the selected identifier in the partial query at the current edit location to form a further developed query.

Abstract: A computer-implemented method includes providing a user interface (UI) that allows a user to select an existing database having cloud storage volumes that contain historical data of one or more customers. A first command input on the UI replicates the existing database is to create one or more new databases. Each of the new databases has new cloud storage volumes created by taking a snapshot of a corresponding one of the volumes of the existing database. Each new database contains the historical data of the existing database such that a new set of databases results. A mapping algorithm is executed in a cloud-computing instance that maps the historical data of each of the one or more customers to produce a shard map. The mapping algorithm includes a round-robin partitioning of the historical data striped by date in a circular order across the new set of databases.
