Abstract: Methods, systems, and computer storage media for providing a multilayer processing engine of a multilayer processing system. The multilayer processing engine supports an event layer, a metadata layer, and a multi-tier processing layer. The metadata layer can refer to a functional layer that operates via a sequential hierarchy of functional layers (i.e., event layer and multi-tier processing layer) to analyze incoming event streams and configure a downstream processing configuration. The metadata layer provides for dynamic metadata-based configuration of downstream processing of data associated with the event layer and the multi-tier processing layer. The multilayer processing system can be a data analytics system—operating via a serverless distributed computing system.
