Abstract: A database system may include a database service and a separate distributed storage service. The database service (or a database engine head node thereof) may be responsible for query parsing, optimization, and execution, transactionality, and consistency, while the storage service may be responsible for generating data pages from redo log records and for durability of those data pages. For example, in response to a write request directed to a particular data page, the database engine head node may generate a redo log record and send it, but not the data page, to a storage service node. The storage service node may store the redo log record and return a write acknowledgement to the database service prior to applying the redo log record. The server node may apply the redo log record and other redo log records to a previously stored version of the data page to create a current version.

The control circuitry is further configured to filter the set of system log data, establish a second connection with a remote computing device using the network interface, and transmit a subset of system log data to the remote computing device via the network interface.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for providing search results automatically to a user of a computing device. A spoken input provided by a user to a computing device is received. The spoken input is transmitted to a computer server system that is remote from the computing device. Search result information that is responsive to the spoken input is receiving by the computing device and in response to the transmitted spoken input. An alert is provided to the user that the device will connect the user to a target of the search result information if the user does not intervene to stop the connecting of the user. The user is connected to the target of the search result information based on a determination that the user has not intervened to stop the connecting of the user.

Abstract: Techniques for visual data preparation are described. An interactive visual data preparation service provides a user with a graphical user interface that presents values from a sample taken of a dataset along with statistical information associated with those values. A user uses the graphical user interface to test out various transformations to the sample dataset by applying transformations and viewing near-immediate results of those transformations as applied to the sample. The desired set of transformations is represented as a recipe object, which can be used to perform data preparation against the overall dataset or other datasets on behalf of the user or other users.

Abstract: A node mask of a global metadata structure entry representing an MD portion in GM may be updated when an entry of a local MD table representing the MD portion is removed in response to receiving an IO operation, without negatively impacting performance of the IO operation. An update process that is independent of the process executing the IO operation may update the node mask so that performance of the IO operation is not negatively affected. In response to the entry for the MD portion being removed from the local MD table, an entry may be added to a queue. The update process may include accessing the entries in the queue, and, for each entry, updating the node mask (e.g., clearing a bit representing the processing node) and removing the entry from the queue.

Abstract: Responsibility for protecting a distributed file system is split across different client hosts. Each client host is assigned a subset of the distributed file system to backup. An index host is identified to create a common namespace under which different client file indexes generated by the different client hosts during backups of respective subsets of the file system will be maintained. During backups, different client file indexes are received from the different client hosts. The client file indexes include metadata about files in the file system included in the backups. Each of the different client file indexes are associated to the same common namespace to provide a unified view of all files across all subsets of the file system that have been backed up by the different client hosts.

Abstract: A system is provided for configuring legacy file-based workflows to remotely and dynamically access media essence. An example system includes a filename generator that dynamically generates a filename for corresponding media content in an essence store in response to a selection by a file-based workflow application running on a media production computing device. The system includes an identity file generator that generates a respective identity file for the selected content and that includes the generated filename. Furthermore, the system includes a content API that queries an essence access database using the generated identity file to obtain metadata that indicates access information for the media content. The content API then configures the file-based workflow application to access the media content from the essence store based on an accessed track number and byte length of the respective media content accessed in response to the query of the media essence access database.

In some example embodiments, the enforcement decision received from the back end system is stored, the stored enforcement decision is accessed in response to the receiving of the request, and the request is responded to using the accessed enforcement decision.

Abstract: A system reduces the time and resources needed to search a large dataset by preprocessing the dataset prior to receiving a query. Generally, the system evaluates and combines rules that govern the validity of the data. The system combines rules to determine conditions under which data objects in the dataset are invalid. After a query is issued, the system quickly eliminates data objects from the response by applying the conditions rather than the individual rules to the data objects.
