Abstract: A data structure is specialized in efficiently representing a key-value pair in a highly optimized way. The data structure is a pointer in a traversal graph that takes advantage of constant time traversal for all operations. The data structure has specific instructions for inserting data nodes, router nodes, and how the expansion or collapse of the graph works. The data structure can be applied where the time to get the result back is most prominent. The data structure can be used to reduce the memory footprint to reach the data that is being searched and achieve a worst-case time complexity in constant time.

Abstract: Techniques to efficiently assign available workers to executing multiple graph queries concurrently on a distributed graph database are disclosed. The techniques comprise a runtime engine assigning multiple workers to executing portions of multiple graph queries, each worker in each assignment asynchronously executing a portion of a graph query within a parallel-while construct that includes return statements at different locations, and the runtime engine reassigning a worker to executing another portion of the same or a different graph query to optimize the overall performance of all workers.

Abstract: Described herein is a system for syncing asynchronously received sequential data from disparate sources. In an embodiment, a central system may receive data transmissions from disparate sources. Each data transmission includes a timestamp and an identifier of the disparate source. The central system may sort the data from the data transmissions of disparate sources in chronological order based on the timestamps. The central system may group the data based on the identifier of the disparate source and normalize the data of the data transmissions to be in a specified format. The central system may store the normalized data of the data transmission in a data storage facility based on the identifier of the disparate source and the sorted order of the data.

Abstract: Example systems and methods for cloning catalog objects are described. In one implementation, a method includes creating a second catalog object by mapping a second portion of second metadata of the second catalog object to same data of a same data file as a first portion of first metadata of a first catalog object, and, in response to a data storage or data retrieval request directed to the second catalog object, deleting data associated with the second portion of the second metadata from the second catalog object independently of the first catalog object.

Abstract: An input switching circuit dynamically connects, based on an input mapping table, input streams to inputs of a wavefront pre-transform circuit. An output switching circuit dynamically connects, based on an output mapping table, output data at outputs of the wavefront pre-transform circuit to transport streams. A controller controls, based on a wiping command, at least one of the input and output switching circuits to alter at least one of the input and output mapping tables such that the at least one of the input and output switching circuits is disabled for connection. A first subset of the transport streams operates in a foreground mode available to a user and is transported for storage in remote storage sites at a network and a second subset of the transport streams operates in a background mode available to an administrator and is not transported for storage in the remote storage sites.

Abstract: Methods, systems, and computer program products are provided for creating a resource management testing environment. An initial population of databases is established in a database ring, having an in initial count of databases and different types of databases that are determined based on an initial database population model. The initial population model receives ring classification information for the database ring from a ring grouping model. A sequence of database population-change events is generated based on a model, to change the population of the databases over time in the ring. An orchestration framework performs testing of resource manager operations based on the model-defined initial population of databases and the model-defined populations of databases changed over time. Model-defined resource usage metrics for each database are utilized to test the resource manager operations. Resource usage metrics and database add/drop events of a production system are used to train the models.

The method also includes monitoring the file for an event that accesses the file, detecting a read access event occurring on the file, and determining a creation of a derivative file generated as a result of the read access event. The method further includes registering the derivative file into the reference table and indicating an association between the derivative file and the file in the reference table.

Abstract: Techniques are disclosed relating to processing database transactions that include application operations defined by different object relational mapping (ORM) libraries. A transaction router module executing on a computer system receives, from an application, a request for a first database transaction, where the first database transaction includes first and second application operations. The transaction router module then translates the first application operation to one or more first database operations using a first ORM library and the second application operation to one or more second database operations using a second ORM library. Then, the transaction router module determines one or more database connections for the one or more first database operations and the one or more second database operations. Such techniques may advantageously allow applications to switch between using different persistence frameworks and message broker frameworks without substantial adjustments to application code.

Abstract: In some aspects, the disclosure is directed to methods and systems for secure and authenticated tracking of entity possession via a lightweight centralized or distributed ledger. Ownership records of different entities may be recorded on an immutable ledger such that provenance of the entities is verifiable and a user cannot create or counterfeit an entity. In some implementations, the system may store metadata of entities in a separate database that may store records for each entity and correspond to the respective entity's virtual identifier, enabling the ledger records to contain much less data, saving memory resources and the energy that is required to maintain the ledger. In some implementations, distributed incremental values may be provided to members of an ownership or possession chain of an entity, which may encourage compliance, reporting of ownership transfer, and encourage additional transfers.

Abstract: Embodiments of the present disclosure provide techniques for efficiently and accurately performing propagation of search-head specific configuration customizations across multiple individual configuration files of search heads of a cluster for a consistent user experience. The cluster of search heads may be synchronized such that the search heads operate to receive the configuration or knowledge object customizations from one or more clients from a central or lead search head. To reduce the amount of data that is transferred during propagation, the list of configuration or knowledge object customizations maintained in each search head is filtered from the list of the lead search head until a divergence point is determined. Once determined and communicated to the lead search head, the lead search head sends the configuration and knowledge object customization data that is absent from the internal list of the member search head.
