Abstract: Systems and methods for determining whether an ambiguous statement applies to a first query or second query. In some aspects, the system includes control circuitry that receives a first search query from a user. The control circuitry determines a syntactic mapping and contextual mapping of the first query. The control circuitry receives a second search query following the first search query. The control circuitry merges the queries. The control circuitry determines whether syntactic mappings for the second query and the portion of the merged query corresponding to the second query are equivalent. In response to determining that the second syntactic mapping and the portion of the third syntactic mapping are equivalent, the control circuitry selects a contextual mapping of the second or merged query based on user contextual information. The control circuitry determines a media asset from the media assets that is related to the first and second queries.

Abstract: One or more techniques and/or computing devices are provided for managing an arbitrary set of storage items using a granset. For example, a storage controller may host a plurality of storage items and/or logical unit numbers (LUNs). A subset of the storage items are grouped into a consistency group. A granset is created for tracking, managing, and/or providing access to the storage items within the consistency group. For example, the granset comprises application programming interfaces (APIs) and/or properties used to provide certain levels of access to the storage items (e.g., read access, write access, no access), redirect operations to access either data of an active file system or to a snapshot, fence certain operations (e.g., rename and delete operations), and/or other properties that apply to each storage item within the consistency group. Thus, the granset provides a persistent on-disk layout used to manage an arbitrary set of storage items.

Abstract: Techniques are described herein for managing transactions between data consumers and data providers using a blockchain.

Abstract: Implementations of the present specification provide a method and an apparatus for obtaining a number for a transaction-accessed variable in parallel in a blockchain. The method includes: for a first variable in a first transaction, calculating a hash value m corresponding to a variable name of the first variable, the hash value m being a value in pre-determined M values; performing the following atomic operation on an mth bit in a bitmap in a shared memory: reading a current first value of the mth bit, setting the mth bit to 1, and returning the first value, the bitmap having M bits, and initial values of the M bits being 0; in response to the first value being 0, obtaining a first number uniquely corresponding to the first variable, the first number being a value in pre-determined N values, and N being less than M; and setting a value of an mth element in a mapping array in the shared memory based on the first number, the mapping array including a total of M elements.

Abstract: This application relates to multi-level replication filtering for a distributed database. A primary node of the database can generate log records that describe write requests performed to the database. The primary node can, in some embodiments, identify a portion of the data of the database that is stored at a second node, such as data stored by a read replica node that can be used in responding to read requests from clients. The primary node can select log records that are applicable to this identified portion of the data to send to the second node. Log records are not selected based on a determination that those unselected log records are not applicable to the identified portion of the data. The primary node can then send the selected log records to the second node, for the second node to apply the log records to its stored database data.
