In-memory time series database and processing in a distributed environment

Abstract

This disclosure describes methods, systems, and computer-readable media for accessing information that describes a hierarchical schema for assembling multiple time series of data in a distributed manner. The hierarchical schema associates each of the time series with a particular level of the hierarchical schema and prescribes a structure of relationships between time series assigned to different levels of the hierarchical schema. Multiple time series associated with a lowest level of the hierarchical schema are assembled by inventorying a portion of a data set. Multiple time series associated with an intermediate level of the hierarchical schema are assembled by aggregating the time series associated with the lowest level based on the structure of nested relationships. Also, multiple additional time series that are associated with the intermediate level and which were assembled by other grid-computing devices are received. After the time series are assembled, they are made available for processing to facilitate parallelized forecasting.
