摘要： A system to manage clustering vertices of a streaming graph includes a memory storing a computer program, a vertex structure storing vertices of the graph, and a cluster structure storing clusters of the graph, and a processor. Each cluster structure comprises a plurality of edge structures represent edges of the graph and each edge structure comprises two of the vertices. The processor is configured to execute the program to cluster the vertices using the structures and a maximum cluster size that is constant.

摘要： In one embodiment, the invention comprises partial fault tolerant stream processing applications. One embodiment of a method for implementing partial fault tolerance in a stream processing application comprising a plurality of stream operators includes: defining a quality score function that expresses how well the application is performing quantitatively, injecting a fault into at least one of the plurality of operators, assessing an impact of the fault on the quality score function, and selecting at least one partial fault-tolerant technique for implementation in the application based on the quantitative metric-driven assessment.

摘要： A streams manager intelligently restores multiple consistent regions of streaming applications in a streaming environment to increase performance and reduce overloading of other operators and resources. The streams manager detects a failure that affects multiple consistent regions and determines a preferred schedule to restore the multiple consistent regions by analyzing the relationships of the operators and resources associated with the multiple consistent regions. The streams manager may create a dependency graph that maps the interrelationships of the operators and resources associated with the consistent regions of the streaming application and then consult the dependency graph to determine the schedule to restore the multiple consistent regions affected by the failure.
