Abstract: One example method includes receiving a group of files, two or more of the files being of different respective file types, creating a backup saveset that includes the group of files, classifying each of the files in the backup saveset based in part on the respective file types of the files, assigning a respective storage media type to each of the classified files in the backup saveset, and transmitting the backup saveset to a storage site.

Abstract: Provided are techniques for role reversal of primary and secondary sites with minimal replication delay. During a backup phase, an Input/Output (I/O) operation selected from a group comprising a create operation and a rename operation is received with one or more local attributes of a local file. The I/O operation is processed to generate one or more remote attributes. The one or more local attributes are stored with the one or more remote attributes. During a reversed phase, a write operation for the remote file is processed, and, the write operation is sent to the primary replication system with the one or more local attributes, where the primary replication system uses a local file handle in the one or more local attributes to access the local file for processing the write operation to sync the local file with the remote file.

Abstract: The disclosed technologies are capable of selectively using data structure operations for path query evaluation. One technique involves reading a query that traverses at least two nodes and at least one edge of a graph in a graph database; compiling the query into a set of variables and a set of constraints, where the set of variables and the set of constraints correspond to the two nodes and the one edge of the graph; creating an in-memory data structure that comprises a table; using the set of variables and the set of constraints to determine an operation that is performable using the in-memory data structure; checking for an existence of a condition relating to the in-memory data structure or the operation; skipping the operation if the condition exists or executing the operation if the condition does not exist; and storing a set of intermediate query results in the table.

Abstract: Described is a system for intelligent re-tiering of backup data stored on a cloud-based object storage. More specifically, the system may re-tier objects such that the system retains the ability to efficiently perform a full restore of backup data even when incremental backups are performed to a cloud-based object storage. To provide such a capability, the system may maintain a specialized metadata database that stores information indicating the backup time for each backup, and a list of objects required to perform a full restore to each of the backup times. Accordingly, when using a threshold time (e.g. expiry) to select object candidates for re-tiering, the system may leverage the metadata database to ensure that objects that may still need to be referenced are not unnecessarily moved to a lower storage tier.

Abstract: This application provides a search apparatus, including a global dispatcher, a global arbiter, and N search engines. The N search engines can access a first search table. The global dispatcher is configured to: determine that a first search keyword is corresponding to the first search table and dispatch the first search keyword to the N search engines. Each search engine is configured to: search, according to a first search algorithm, one subtable to determine whether an entry that matches the first search keyword exists; and output a search result to the global arbiter. The global arbiter is configured to arbitrate the search result output by each search engine, to obtain a search result corresponding to the first search table.

Abstract: In some examples, a first computing device may receive, from a server, an indication that the server has recovered data. For instance, the first computing device may store metadata including a mapping for one or more file systems accessed by one or more client devices. Furthermore, a second computing device may store a copy of the mapping stored on the first computing device. The first computing device may receive, from the server, a mapping of the one or more file systems determined by the server based on the recovered data. The first computing device may compare the mapping from the server with the mapping of the one or more file systems on the first computing device, and may send, to the server, information about changes determined between the two mappings to enable the server to update the mapping on the server based on the changes.

Abstract: A workbook management system provides a master branch of a data pipeline comprising a pointer(s) to a snapshot(s) of an initial dataset(s), a first logic, and a pointer(s) to a snapshot(s) of a first derived dataset(s) resulting from applying the first logic to the initial dataset(s). Responsive to user input requesting a test branch corresponding to the master branch, the system creates the test branch comprising the pointer(s) to the snapshot(s) of the initial dataset(s) and a copy of the first logic. The system receives a request to modify the test branch comprising at least one change to the copy of the first logic, and modifies the test branch independently of the master branch to include second logic reflecting the at least one change to the copy of the first logic, the pointer(s) to the snapshot(s) of the initial dataset(s), and a pointer(s) to snapshot(s) of a second derived dataset(s) resulting from applying the second logic to the initial dataset(s).

Abstract: An online system generates a cluster group and uses membership in the cluster group as an eligibility criteria for presenting a content item. The online system receives a request from a third party system to present the content item. The online system also receives identification information about users who have visited webpages associated with the third party system and descriptive information associated with the webpages. Based on the descriptive information, the online system extracts tags for the webpages and classifies the webpages into one or more categories that include a category associated with the content item. The online system generates a seed group that includes users who visited webpages in the category associated with the content item. The online system further expands the seed group to a cluster group by applying a cluster model to one or more characteristics of each candidate user not included in the seed group.

Abstract: A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being migrated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been migrated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.
