  • Publication number: 20220182429
    Abstract: A data division unit divides each of a plurality of stream data pieces input in a time series into divided data by a predetermined time unit. Each of a plurality of data processing units executes predetermined processing on the stream data. An allocation determination unit determines a combination of the divided data of each of the plurality of stream data pieces and the data processing unit executing the predetermined processing on each of the divided data pieces based on a correlation between processing loads on the plurality of stream data pieces. A data distribution unit distributes the divided data to the data processing unit in accordance with the combination determined by the allocation determination unit.

  • Publication number: 20200192709
    Abstract: [Problem] To provide an analysis node capable of appropriately managing computational resources in relation to load fluctuation, and continuously performing analysis processing with high throughput. [Solution] An analysis node includes an analysis execution means 1, a content variation observation means 2, and a resource allocation means 3. The analysis execution means 1 performs analysis processing that includes a plurality of steps including at least a pre-stage step and a post-stage step, by computational resources allocated to each of the steps. The content variation observation means 2 observes, as content variation observation information, content change of processing-target data at the pre-stage step. The resource allocation means 3 predicts fluctuation in a processing load at the post-stage step, based on the content variation observation information, and changes the computational resources allocated to the post-stage step.
