Abstract: A method for improving asynchronous data replication between a primary storage system and a secondary storage system maintains a cache in the primary storage system. The cache includes a higher performance portion and a lower performance portion. The method monitors, in the cache, unmirrored data elements needing to be mirrored, but that have not yet been mirrored, from the primary storage system to the secondary storage system. The method maintains a regular LRU list designating an order in which data elements are demoted from the cache. The method determines whether a data element at an LRU end of the regular LRU list is an unmirrored data element. In the event the data element at the LRU end is an unmirrored data element, the method moves the data element from the higher performance portion to the lower performance portion. A corresponding system and computer program product are also disclosed.

Abstract: Techniques described herein proposes a Dependent Grouping Column Rewrite that simplifies a grouping operation by excluding dependent grouping columns from a group by clause. A non-blocking aggregation function is applied to dependent grouping columns in at least select clauses. Such a simplified grouping operation reduces memory pressure, speeds up grouping operations, and saves compute time, as grouping columns that have no additional effect on the grouping operation are excluded from processing (e.g., hashing and key matching).

Abstract: Methods, systems, and devices for data attribution using frequent pattern analysis are described. In some cases, data stored at a multi-tenant database server may be analyzed to understand various interactions and patterns between data attributes associated with multiple users. The multi-tenant database server may effectively cluster and/or perform calculations on attributes of the data to understand user patterns. In some examples, the multi-tenant database server may determine a change (e.g., a probability change) in the user patterns by removing one or more attributes from the data set and re-performing the analysis. By re-performing the analysis, the multi-tenant database server may attribute a value to individual pieces and combinations of the data in order to indicate the effect that each piece of data has on the analysis.

The history management method performed by at least one processor includes generating a block for being connected to the blockchain from the history information collected in the vehicle, per block, setting a storage destination of a backup of the generated block from among nodes communicable with the vehicle, and sending the backup of the block to the node that is set as the storage destination.

Abstract: Transaction change data replication includes identifying changes being made to a source database as part of an ongoing transaction at a source. The identifying is performed as the changes are made to the source database and as the transaction remains ongoing prior to commit or rollback thereof at the source. The source and a target are in a replication relationship in which data of the source database at the source is replicated to destinations in a target database at the target. The indications of the changes being made to the source are forwarded, to the target, as the transaction remains ongoing prior to commit or rollback thereof, and based on ending the transaction at the source, an indication of the transaction end is sent to the target.

Abstract: An overlay optimizer can enhance the functionality of a write filter using an auxiliary overlay. An overlay optimizer can be loaded above a write filter. Based on the configuration of the write filter's overlay, the overlay optimizer can be configured to implement a volatile or persistent auxiliary overlay and then use the auxiliary overlay to selectively cache artifacts. To minimize the likelihood that the consumption of the write filter's overlay will exceed a critical threshold, the overly optimizer can be provided a list of monitored artifacts. The overlay optimizer can employ the list to selectively move monitored artifacts from the write filter's overlay to the auxiliary overlay when the overlay's consumption reaches a threshold. The overlay optimizer may also selectively allow I/O requests generated by particular applications while redirecting I/O requests generated by other applications.

Abstract: A method, computer program product, and a system to globally serialize transactions where a processor(s) establishes a communications connection a (serialization) resource and a resource manager for a distributed computing system. The processor(s) obtains a first request from an application executing on the resource for access to a global resource managed by the resource manager, for executing a transaction. The processor(s) implements a lock for the global resource in an object store of the resource manager over the communications connection. The processor(s) communicates the lock to the application, which executes the transaction and the processor(s) updates a memory with a record comprising attributes of the lock. The processor(s) obtains a second request from the application to terminate the lock, obtains, identifies the lock for the transaction, in the object store, and updates the object store to delete the lock.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for relevance feedback with faceted search interface. A system provides a first search query to an image search engine for initiating an image search, where the first search query indicates a first search term. The system obtains image metadata from an image collection, and obtains a listing of query refinement terms associated with the first search query from the query refinement data structure. The system determines a listing of search results containing images with one or more facets associated with the listing of query refinement terms. The system then receives user input indicating selection of at least one of the one or more facets of an image in the listing of search results. The system provides a second search query using the first search term and a second search term indicating the selected one or more facets.
