Abstract: Systems, device and techniques are disclosed for receiving a request from a user to add a media item to a playlist at a certain playlist position where the media items in the playlist are provided to other users in a media group. Based on a determination that the requesting user has rights to the requested media item, the requested media item may be added to the playlist at the position. When the playlist reaches the position, the user that added the media item to the playlist may be provided with a first version of the media item and the other users in the group may be provided with a second version of the media item. If the user that requested the item to be added to the playlist is determined not to have rights to the media item, the item is added to a position different than the requested position.

Abstract: Techniques are disclosed for query processing system that can, when queried, generate a result related to one or more connectivity paths and/or one or more network security rules. Network security rules and connectivity paths may be stored in corresponding data structures (e.g., sets of attributes) that may be utilized with a number of set operations. The user may issue a query requesting the system to apply a rule to a path, a set of rules to a set of paths, to identify if one set of rule(s) are equivalent to another set of rule(s), and the like. Utilizing this query processing system can enable a user to identify effects of one or more network rules with respect to traffic being allowed or restricted along particular connectivity paths between components of the system.

Abstract: Methods, systems, and computer-readable media for renaming a database table with minimized application downtime are disclosed. A database receives a table rename request for a table having a first table name. Routing metadata comprises a mapping of the first table name to a table identifier and a mapping of the table identifier to one or more partitions. The table rename request indicates a second table name. The database generates updated routing metadata responsive to the table rename request. The updated routing metadata comprises a mapping of the second table name to the table identifier and the mapping of the table identifier to the one or more partitions. The database receives, from a client application, one or more access requests indicating the second table name. The database routes the one or more access requests to the one or more partitions based at least in part on the updated routing metadata.

Abstract: Certain aspects of the present disclosure provide techniques for processing east-west queries in an application programming interface (API) generated for a plurality of associated services. The method generally includes receiving, at a request gateway from a requesting service, a request to invoke a function exposed by a first service through the API.

A response message including objects associated with the referenced entities is consumed. The function is executed based on the objects associated with the referenced entities, and the result generated by executing the function is returned to the requesting service.

In some cases, one or more queries are applied (e.g.

Abstract: Various embodiments for providing a data transfer and management system are described herein. An embodiment operates by determining that data of a column is stored in a column loadable format in which all of the data of the column is moved from the disk storage location to a memory responsive to a data request. A data vector that identifies a plurality of value IDs corresponding to at least a subset of the plurality of rows of the column, is identified. A page format that provides that a portion of the data of the column across a subset of the plurality of rows is moved from the second disk storage location into the memory responsive to the data request is determined. The entries of the data vector are requested, converted from column loadable format into the page persistent format, and stored across one or more memory pages.

Abstract: This disclosure describes various ways in which a client agent can be incorporated into multiple virtual machines of a server cluster to keep track of the location of each instance of services running on the server cluster and facilitate rapid connection of different services on the server cluster as needed. When a first service requests connection to a second service, a client agent co-located with the first service is able to forward the request to a virtual network interface card (VNIC) associated with the second service. The VNIC is configured to forward the request to an available instance of the second service. The location of the services are determined and stored on one or more service registries right after the service instances are instantiated, removing the need for a search when new requests are received.

Abstract: The present invention provides a method of synchronous deletion for distributed storage system. According to the present invention, after a first host accesses one or more first datum, a first data list and a second data list will be created in a blockchain network corresponding to the modification of the data in the first host. Then the first data list and the second data list are used to update a second host. Accordingly, by taking advantages of the indestructibility of the blockchain technology, the existence of the first data list and the second data list will be maintained. Then the second data accessed by the second host will still be consistent even the first host has modified them. In addition, a hardware safety module can be further adopted to ensure the correctness of the execution file in the second host.

Abstract: An operations integration processor generating tag names from an array of objects in a language-independent data format different than a tag format for integration with a tag-based control and data acquisition system. The operations integration processor receives a response from a web service and parses the response to identify one or more objects and corresponding values in the array contained in the response. The response includes an array of objects and is in a language-independent data format different than a tag format. The processor configures a selected object of the array to act as a unique index for the array of objects and generates one or more tag names from the parsed response. The tag names each represent a tag having at least one of an object and a value associated with it based on the information provided in the response. The generated tag names include the selected object in an array index part thereof.

Abstract: An analysis system connects to a set of data sources and perform natural language questions based on the data sources. The analysis system connects with the data sources and retrieves metadata describing data assets stored in each data source. The analysis system generates an execution plan for the natural language question. The analysis system finds data assets that match the received question based on the metadata. The analysis system ranks the data assets and presents the ranked data assets to users for allowing users to modify the execution plan. The analysis system may use execution plans of previously stored questions for executing new questions. The analysis system supports selective preprocessing of data to increase the data quality.
