摘要： A system, method, and computer readable medium for reducing message flow on a message bus are disclosed. The method includes determining if at least one logical operator in a plurality of logical operators requires processing on a given physical processing node in a group of physical nodes. The logical operator is pinned to the given physical processing node. The pinning prevents any subsequent reassignment of the logical operator to another physical processing node. Each logical operator in the plurality of logical operators is assigned to an initial physical processing node in the group of physical processing nodes on a message bus. A determination is made as to whether at least one logical operating in the plurality of logical operators needs to be reassigned to a different physical processing node. The at least one logical operator is reassigned to the different physical processing node.

摘要： An index scan processor and method to perform concurrent scans of stored indexed data. An indexed data scanner performs a first scan of stored data by sequentially scanning through an index data structure and maintains, over a duration of the first scan, a first scan current scan location within the index data structure that indicates a currently accessed record within the stored data structure for the first scan. A scan manager accepts a request for a second scan of the stored data, determines, during the performing the first scan, a starting index scan location within the index data structure for the second scan that is sufficiently near the first scan current index scan location to cause records indicated by the starting location index to be stored within a buffer due to the performing the first scan, and starts the second scan at the starting location and proceeding to the second end key.

摘要： Techniques are disclosed for multi-granularity hierarchical aggregate selection based on update, storage and response constraints. For example, for a temporal hierarchy of aggregation statistics associated with a plurality of database records, wherein the temporal hierarchy comprises two or more aggregation statistics levels and each level has a different temporal granularity associated therewith, a method comprises iteratively modifying the temporal hierarchy to at least one of: (a) minimize a storage usage cost while satisfying a temporal hierarchy update constraint and a query response time constraint; (b) reduce a temporal hierarchy update time and a query response time while satisfying a storage usage constraint; and (c) minimize a query response time for frequently applied queries that do not shift in time while satisfying the storage usage constraint, wherein the resulting temporal hierarchy that achieves at least one of (a), (b) and (c) is identified as an optimal temporal hierarchy.

摘要： A method is provided for compressing results of a join query. A join order of a result set comprising multiple tuples is determined from the join query, and a nested hierarchy of dictionaries is maintained based on the join order. The nested hierarchy of dictionaries is used to encode each of the tuples of the result set so as to produce an encode tuple, and each of the encoded tuples is transmitted to a client system. Also provided is a method for decompressing results of a join query.
