摘要： A method for scheduling atomic update jobs to a streaming data warehouse includes allocating execution tracks for executing the update jobs. The tracks may be assigned a portion of available processor utilization and memory. A database table may be associated with a given track. An update job directed to the database table may be dispatched to the given track for the database table, when the track is available. When the track is not available, the update job may be executed on a different track. Furthermore, pending update jobs directed to common database tables may be combined and separated in certain transient conditions.
摘要翻译：用于将原子更新作业调度到流数据仓库的方法包括分配用于执行更新作业的执行轨迹。可以为轨道分配可用的处理器利用率和存储器的一部分。数据库表可以与给定的轨道相关联。当轨道可用时，定向到数据库表的更新作业可以被分派到数据库表的给定轨道。当轨道不可用时，可以在不同的轨道上执行更新作业。此外，针对公共数据库表的待定更新作业可以在特定的瞬态条件下组合和分离。

摘要： Methods, systems, and products characterize consistency of data in a stream warehouse. A warehouse table is derived from a continuously received a stream of data. The warehouse table is stored in memory as a plurality of temporal partitions, with each temporal partition storing data within a contiguous range of time. A level of consistency is assigned to each temporal partition in the warehouse table.

摘要： Two methods and computer-readable medium for obtaining information using field group unpacking functions. The first method obtains information using field group unpacking functions by identifying an optimized unpacking function from field group unpacking functions, and an optimized unpacking function is used to unpack a field associated with the data stream. The second method obtains information using field group unpacking functions by identifying an optimized unpacking function from the field group unpacking functions. Then, a prefilter is applied and associated with the optimized unpacking functions and used to unpack a field associated with the data stream. The computer-readable medium obtains field group unpacking functions for execution by a computing device using field group unpacking functions that identify an optimized unpacking function from the field group unpacking functions, and use an optimized unpacking function to unpack a field associated with the data stream.

摘要： A method and system are disclosed for operating a high speed data stream management system which runs a query plan including a set of queries on a data feed in the form of a stream of tuples. A predicate prefilter is placed outside the query plan upstream of the set of queries, and includes predicates selected from those used by the queries. Predicates are selected for inclusion in the prefilter based on a cost heuristic, and predicates are combined into composites using a rectangle mapping heuristic. The prefilter evaluates the presence of individual and composite predicates in the tuples and returns a bit vector for each tuple with bits representing the presence or absence of predicates in the tuple. A bit signature is assigned to each query to represent the predicates related to that query, and a query is invoked when the tuple bit vector and the query bit signature are compatible.

摘要： Data tables in data warehouses are updated to minimize staleness and stretch of the data tables. New data is received from external sources and, in response, update requests are generated. Accumulated update requests may be batched. Data tables may be weighted to affect the order in which update requests are serviced.

摘要： Techniques are disclosed for generating conditional functional dependency (CFD) pattern tableaux having the desirable properties of support, confidence and parsimony. These techniques include both a greedy algorithm for generating a tableau and, for large data sets, an “on-demand” algorithm that outperforms the basic greedy algorithm in running time by an order of magnitude. In addition, a range tableau, as a generalization of a pattern tableau, can achieve even more parsimony.
