  • 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.
