Abstract: A computing device executing software displays a view of a search assignment in a user interface to a learning platform. The device receives user input comprising search terms associated with the search assignment, and generates queries based on the user input. The device submits the queries to a search engine, whereupon the search engine performs searches based on the queries, and the device displays the results. As a user evaluates resources provided in the results, the device updates the user interface to include an option selectable for adding evaluated ones of the resources to a collection of resources for the search assignment. In response to the user selecting the option with respect to a resource of the evaluated ones of the resources, the device adds the resource to the collection of resources.

Abstract: Some embodiments provide a method for determining a relatedness of content items to categories. The method identifies a particular content item, a relevancy score associated with the particular content item, and a set of categories to which the particular content item is classified as related. Based on a set of glossaries associated with the set of categories, the method calculates a set of affinity scores that each represents a degree of relevancy between the particular content item and a category in the set of categories. The method modifies the relevancy score associated with the particular content item based on the calculated set of affinity scores.

Abstract: A computerized method for implementing a matching platform for entities includes a real-time processing layer using real-time linking on an input data stream, and a high-throughput layer linking entities from a batch data source stream. The real-time linking results are stored in a state change store and the high-throughput linking results are stored in a state store. On-demand linking uses the state change store and the state store. A lambda switch ensures that the entity states remain consistent when the on-demand linking switches from an older generation of the state store and the stage change store to a newer generation of the state store and the state change store. These stores are implemented in an entity database that parses queries into instructions and creates an instruction stream to control entity matching.

Abstract: A database system is provided, including a first global transaction manager (GTM), a first data node) DN, and a coordinator node (CN). The CN is configured to send a query to the first DN. The first DN is configured to, in response to the query, determine a target commit sequence number (CSN), determine a committed transaction on the first DN based on the target CSN, and determine a query result corresponding to the query based on the committed transaction. The target CSN is allocated by the first GTM. The target CSN is used to distinguish between the committed transaction and an active transaction on the first DN. The active transaction is a transaction that is being executed. In addition, a corresponding transaction management method is provided. The CSN is used to replace an active transaction linked list. This reduces network traffic and improves concurrency and scalability of the database system.

Abstract: In some implementations, events measured at various points in time may be organized in a data structure that defines an event represented by a document. In particular, events can be organized in columns of documents referred to as buckets. These buckets may be indexed using B-trees by addressing metadata values or value ranges. Buckets may be defined by periods of time. Documents may also be geoindexed and stored in one or more locations in a distributed computer network. One or more secondary indexes may be created based on time and/or metadata values within documents.

Abstract: In one embodiment, a first entry in a first database is modified to include data from a highest-ranked one of one or more available data tables that correspond to the first entry. Each of one or more characters fields of the modified first entry are converted into a respective one or more first-entry tokens, and each of one or more character fields of each of a plurality of second entries in a second database is converted into a respective one or more second-entry tokens. The first-entry tokens are compared to the second-entry tokens, and, in response to the comparison, it is determined whether the first entry matches one of the second entries. In response to determining that the first entry matches one of the second entries, the first entry and the matching second entry are associated with one another in one or both the first and second databases.

Abstract: A compaction policy imposing soft limits to optimize system efficiency is used to select various rowsets on which to perform compaction, each rowset storing keys within an interval called a keyspace. For example, the disclosed compaction policy results in a decrease in a height of the tablet, removes overlapping rowsets, and creates smaller sized rowsets. The compaction policy is based on the linear relationship shared between the keyspace height and the cost associated with performing an operation (e.g., an insert operation) in that keyspace. Accordingly, various factors determining which rowsets are to be compacted, how large the compacted rowsets are to be made, and when to perform the compaction, are considered within the disclosed compaction policy. Furthermore, a system and method for performing compaction on the selected datasets in a log-structured database is also provided.

Abstract: An amount of expiration time extension for one or more objects associated with a first archive of a first snapshot of a source storage is determined based at least in part on a second data management policy associated with a second archive and one or more dynamically determined metrics.

Abstract: Whether a logical query plan to derive a target dataset from one or more source datasets is available is determined. Responsive to determining that the logical query plan is not available for the transformation code in the first programming language, relationships between the source columns of the one or more source datasets and the respective target columns of the target dataset are inferred. Target column metadata for a target column of the target dataset is generated. The target column metadata reflects the inferred relationships between the source columns of the one or more source datasets and the respective target columns. The target column metadata for the target column of the target dataset is stored.

Abstract: The present disclosure involves systems, software, and computer implemented methods for efficiently accessing shared operators in database query plans. One example method includes identifying a query plan tree that represents a query plan for a database query. A node identifier of each node of the query plan tree is initialized to a default node identifier value and a global node identifier counter for the query plan tree is initialized. The query plan tree is traversed including determining whether a node identifier of a current node equals the default node identifier value. If the node identifier of the current node equals the default node identifier value, the current node is processed, the node identifier of the current node is set to a current value of the global node identifier counter, and the global node identifier counter is incremented. Otherwise processing of the current node is skipped.

Abstract: A database manager is disclosed that retrieves database records having binary encoded data from a database and instantiating objects in an in-memory database. Binary encoding compresses data, allowing many subrecords to be stored a single blob field of a database record. Retrieving chunks from storage reduces transfer time by reducing the size of data and the number of operations needed to retrieve all the subrecords. The database manager receives database access requests from a database application. Changes made to the database objects and committed by the application are written back to the persistent database as versioned delta records. In a subsequent session, loading the database from storage includes first loading the most recent snapshot record, then applying changes to the data stored in delta records. The changes stored in the delta records are applied to the data in the snapshot record in the order in which they were made.
