Abstract: Embodiments for performing load balancing in a filesystem of a distributed network comprising worker nodes accessing shared resources that are controlled by distributed locks to grant and prevent access from clients, by assigning a range of directory entries to each worker node, and providing feedback from each worker node to a load balancer to expose an internal state of acquired resources and other parameters of each worker node. In response to periodic updates of the directory ranges to be collocated, the system maintains directory ranges in each worker so that complete subtrees of the directory tree fit in a single range assigned to a worker. Upon receipt of a client request to access a data asset, the load balancer selects the most optimum worker to satisfy the request based on the worker internal states and other parameters.

Abstract: During the presentation of an interactive video, a user may interact with the interactive video by, e.g., making selections, choosing options, etc. related to one or more aspects of the interactive video. Such events and details regarding the events may be recorded, stored, and analyzed in the context of one or more campaigns associated with the interactive video, such as marketing campaigns, advertising campaigns, interactive examinations, etc. Once the details regarding the events have been stored, reports may be extracted based upon the details detailing any desired information relevant to the one or more campaigns.

Abstract: The present specification describes a computer-implemented method. According to the method, an electronic file to be stored is received and a first context determined for the electronic file. The electronic file is split into multiple segments such that the first context of the electronic file is not discernible from any segment. The multiple segments are then distributed amongst multiple remote storage devices.

According to one embodiment, a dynamic schema data system implements a query dialect that is configured to expose underlying flexible schemas of the dynamic schema data system, any structured data, unstructured or partially structured data, and expressive querying native to the dynamic schema system in a language that is compatible with structured queries, and for example, compatible with SQL-92. In further embodiments, the query dialect is configured to enable consistency with existing dynamic schema database query semantics (e.g., the known MongoDB database and associated query semantics).

Abstract: A computing server may continuously update a set of nodes that are addable to a data tree based on past interactions of the user with one or more nodes. The computing server may track a recently interacted set of interacted nodes with which the user has interacted within a number of past interactions. The computing server may select a pool of candidate nodes based on the recently interacted set. At least one of the candidate nodes is within a domain boundary of one of the interacted nodes that is in the recently interacted set. The domain boundary may be determined by the degree of relationship. The computing server may present one or more candidate nodes in the pool as a version of the continuously updated set of nodes. The computing server may update the pool of candidate nodes as additional interactions performed by the user updates the recently interacted set.

Abstract: A system and method are presented that utilize separate append-only arrays to track metadata and real data for a file. All modifications to the file result in metadata records being appended to the end of the metadata array. Write modification commands cause real data to be appended to the file data array. The location of real data on the file data array is identified by a record in the metadata array. Modification commands can be grouped into sets, which complete as a set. Modification sets can rely upon the completeness of prior sets. Read-like commands cause the creation of a virtual array based upon the records of the metadata array. The created virtual array has the same size as the actual file but does not contain the real data for the file. Rather, the virtual file array maps to the actual data stored in the file data array.

Abstract: A memory tier including persistent memory (PMEM) devices is established in nodes of a cluster system having a deduplicated file system. At least a portion of metadata generated by the deduplicated file system is persisted to the memory tier. The portion of metadata includes an index of fingerprints corresponding to data segments stored by the deduplicated file system to a storage pool. A determination is made that an instance of the deduplicated file system has failed. A new instance of the deduplicated file system is started to recover file system services by loading the index of fingerprints from the memory tier.

Abstract: The disclosed system links an individual dataset to a database. The system receives a target individual dataset associated with a target individual and identifies candidate individual datasets that are potentially related to the target individual dataset. The system identifies a related individual dataset that has data bits that match some data bits in the target individual dataset. The system then identifies a parent node that is a common parent node to both the target individual dataset and the related individual dataset. The system retrieves a data tree that the parent node belongs to with the data tree containing information describing inter-relationships among datasets in the data tree. A node in the data tree is identified to assign the target individual dataset based on strings of matched data bits and number of the matched strings between the target individual dataset and the datasets in the data tree.

Abstract: The disclosed embodiments provide a system for processing data. During operation, the system determines activity features for candidates that match parameters of a search from a moderator of an opportunity, wherein the activity features include an amount of interaction between a candidate and additional moderators and a frequency of visits by the candidate to a platform used to conduct the interaction between the candidate and the additional moderators. Next, the system applies a machine learning model to the activity features to produce activeness scores representing levels of activity of the candidates with respect to the platform. The system then generates a ranking of the candidates according to the activeness scores. Finally, the system outputs at least a portion of the ranking as a set of search results of the search.

Abstract: Methods for improving performance of tiered storage of a data processing service by detecting and reducing thrashing of data blocks between warm and cold storage tiers are disclosed. In order to understand the frequency of hits by incoming queries to data blocks that are not currently stored in the warm storage tier, the elapsed time between query hits to the respective data blocks may be tracked using timers. Times below a given amount of time may be used to indicate thrashing. For example, recently evicted data blocks that are subsequently hit by a query within a short amount of time since eviction may indicate thrashing. In scenarios in which thrashing may be occurring, a threshold corresponding to the number of times a given data block in the cold storage tier receives a query hit before being added to the warm storage tier may be turned on.
