Abstract: Method and apparatus for adding annotations to an index are disclosed. Annotation is defined as any supplemental information that may be stored in an index node in addition to the usual key and data references. Adding annotations to the index opens numerous applicative possibilities, including but not limited to, storing and retrieving aggregation, statistical, and security information pertaining to the indexed data and to the index itself.

Abstract: Evaluation of data models and forecasts is provided, enabling processing of large numbers of forecast scenarios in a production environment. An approach for optimizing the computation for statistical modeling and forecasting is described. This approach includes calculating a recommended number of collected data points, calculating a cap on time to elapse, deciding based on at least one of the recommended number of collected data points and the cap on time to elapse whether to generate a forecast model and generating a forecast model from the collected data points.
