    Abstract: A method and system for providing query aware partitioning are disclosed. For example, the method receives a query plan comprising a plurality of queries, and classifies each one of the plurality of queries. The method computes an optimal partition set for each one of the plurality of queries, and reconciles the optimal partition set of each one of the plurality of queries with at least one subset of queries of the plurality of queries. The method selects at least one reconciled optimal partition set to be used by each query of the plurality of queries, and stores the selected at least one reconciled optimal partition set in a computer readable medium.

    Abstract: A method includes parsing a regular pathway expression into fragments including an anchored fragment and at least one other fragment. A number of the fragments is based on at least a length limitation of the regular pathway expression. The method includes generating an operator directed acyclic graph (DAG) including non-operator nodes, operator nodes, and a root based on at least the anchored fragment. The method includes removing, from the operator DAG, at least one of the non-operator nodes and connecting a first operator node to a second operator node of the operator nodes. The first operator node includes an edge into the at least one removed non-operator node, and the second operator node includes an edge from the at least one removed node. The method includes executing the operator DAG on a graph database to return a pathway set comprising at least one pathway that satisfies the regular pathway expression.

    Abstract: A system may include a processor and an input adapted to communicate with a network. The system may also include memory storing instructions that cause the processor to effectuate operations. The operations may include detecting a plurality of nodes in the network based on data received at the input and for each of a plurality of nodes, instantiating a node data structure. The operations may also include, for each respective node of the plurality of nodes, identifying an edge indicative of a connection between the respective node and a second node of the plurality of nodes, and instantiating a plurality of edge data structures based on the edges. The operations may also include creating a graph database comprising a layered graph based on data structures, the data structures comprising the plurality of node data structures and the plurality of edge data structures.

    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. Metadata can be stored in temporal metadata partitions based upon a time range included in the metadata. Furthermore, metadata can be stored in multiple temporal metadata partitions to which the metadata is relevant. As such, metadata can be stored in manner that allows event data to be understood in the context of temporally accurate and/or relevant metadata. Functionality for executing queries of event data and providing results in view of metadata, as well as the merging of multiple temporal metadata partitions also are disclosed.

    Abstract: Methods, systems, and products schedule updates to stream warehouses. A plurality of execution tracks are allocated in memory, with each execution track assigned a portion of utilization of a processor and a proportionate portion of the memory. A home track is also defined in the plurality of execution tracks. When the home track is unavailable, then a different track in the plurality of execution tracks is selected, and a database update job is dispatched to the different track.
