Abstract: The present disclosure is related to a method and an apparatus for data migration in a database cluster. The method includes obtaining a snapshot of a source data node and recording incremental data in a to-be-migrated data shard in the source data node according to inventory data. The method includes migrating the inventory data to a target data node. The method also includes migrating the incremental data, and during the migration when the unmigrated incremental data satisfies a preset write-lock condition, instructing the source data node to perform a write-lock operation on the to-be-migrated data shard and migrate unmigrated incremental data to the target data node. The method further includes, after the migration of the incremental data is completed, instructing a coordinator node to switch a route corresponding to the to-be-migrated data shard from the source data node to the target data node.

The system can export and/or store the applicable content along with modified metadata. The system can automatically modify metadata according to one or more profiles. Relevant profiles can be determined based on the export mechanism, destination or type of content. The system can add watermarks to indicate metadata modification. The system can display metadata for user modification. The content can include photos, videos or other content.

Abstract: Files are identified for file-level restore by bitmaps of cloud snapshots of a storage volume. The bitmaps comprise a data structure for each snapshot containing record numbers of files of the storage volume and a file status bit for each such file that indicates the presence or absence of the file in the corresponding snapshot. File numbers of files of interest are obtained from record numbers of records in a volume files index of the storage volume. The bitmaps can be searched to locate the snapshots containing particular files of interest without the necessity of mounting and searching the separate snapshots on a virtual machine.

Abstract: Computer-implemented methods, computer-implemented systems, and non-transitory, computer-readable media for data manipulation record storage. One computer-implemented method includes: sending, by a server, one or more manipulation instructions to a database, wherein the one or more manipulation instructions are in a structured query language (SQL) format; receiving, by the server from the database, an execution result of the one or more manipulation instructions; generating, by the server, one or more data records comprising the one or more manipulation instructions and the execution result; and determining, by the server, that a predetermined condition of generating a data block is satisfied; and generating, by the server, the data block that includes at least a portion of the data records.

Abstract: Disclosed is a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for generating search results. A data access module accesses search results data indicative of a plurality items and that is indicative of ranking values of the plurality of items. A controller module generates page data based on the search results data. The controller module selects a first item from the plurality of items. A diversification module accesses a first rule of the page data. The diversification module determines a deviance value and a reordering-cost value of a second item from the plurality of items. The controller module can select, based at least on a first combination of the deviance and the reordering-cost values of the second item, the second item for placement ahead of the first item on the page data.

Abstract: A system and method for salting and fingerprinting database tables, text files, data feeds, and the like, first resorts the data according to a field or fields in the data set. A salting recipe is selected and applied to the sorted data. A fingerprint of the data is captured after sorting and salting. The data is then restored to its original order before being sent to a trusted third party. Because the data owner retains information concerning the sorting sorting sonar technique, salting technique, and the fingerprint, the data owner can reconstruct the unsalted file from the salted file, and can determine if a wild file contains data from the data file. The salting is difficult to detect by the bad actor, even if the bad actor is aware that the data has been salted.

Abstract: The invention relates to computer-implemented method for updating a target table with changes introduced into a source table. New data records are stored into partitions of the source table. An incremental update module copies the new data records from the source table into the target table, thereby assigning a new target partition ID contained within a first value domain to each copied data record. A view specifies a set of visible partition IDs as a union of the first value domain and of a current target partition ID set and allows the execution of database queries selectively on target table partitions having assigned a target partition ID that is element of the visible partition ID set. A batch update module performs an atomic batch update operation that comprises copying partitions of the source table into a respective new partition in the target table.

Abstract: A cloud service provider supports immutable data on its servers and the immutable data is movable across multiple access tiers, in which each access tier affects access performance and cost. In typical implementations, the immutable data may be blobs of unstructured data such as text or binary data, multimedia, among other data types, which are organized into containers that provide a directory for user interaction with the data. Policies are applied at the container-level which regulates user interactions with the containers and the container's blobs. A policy can, for example, prohibit modification and deletion of blobs within a container until a policy's set retention period expires. After expiration of the retention period, the container and that container's blobs may be deleted, but blob modification may still be prohibited. A user interface is configured to enable a user to move containers to other access tiers while the container maintains its policy.

Abstract: Systems and methods for improving a search process are provided. A networked system accesses, from online sources, fashion trend information including pictures illustrating fashion trends. The networked system determines a plurality of top fashion trends, and extracts, using an image detection algorithm, images of fashion items from a picture associated with each of the top fashion trends. Using the extracted images, the networked system performs an image search for matching inventory items. The networked system then generates and stored a plurality of fashion trend user interfaces, whereby the plurality of fashion trend user interfaces each comprise selectable elements that represent the plurality of top fashion trends. At runtime, the networked system receives an indication to initiate a search for fashion by trends, and in response, accesses the plurality of stored fashion trend user interfaces. One of the plurality of stored fashion trend user interfaces is presented on a user device.

Abstract: In one implementation, a method is provided that receives multiple potential listings associated with an entity. A listing is selected from the multiple listings and is designated as a representative listing of the entity. A first request is transmitted to synchronize the representative listing with the entity. Responsive to an indication that a synchronization is complete, a second request is provided to suppress a second listing as a duplicate listing. A confirmation of the second request is received and the suppression of the second listing is verified.
