Abstract: Concepts and technologies are disclosed herein for managing a distributed database. A data management application can obtain a query. The data management application can analyze the query to determine a number of data structures relevant to the query. The data management application also can analyze data stores storing the data structures and move or assign data structures to other data stores within a distributed database. The movement of the data structures within the distributed database can be based upon greedy algorithms for moving data and/or executing queries.

Abstract: Concepts and technologies are disclosed herein for generating and using temporal metadata partitions.

Abstract: A method and system for extracting useful statistics and information and removing a processing module based on the information to enhance a run-time system on a network interface card is disclosed. The run-time system module feeds information derived from a network packet to processing modules which process the information and generate output such as condensed statistics about the packets traveling through the network. The run-time system can be enhanced to included facilities for removing processing modules without replacing the run-time system module.

Abstract: 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.
