A method implements a streaming machine learning platform. The method includes processing event data with a preprocessing application to generate model input data and cardinality data in response to receiving the event data from a streaming application. The method further includes forwarding, using the cardinality data, the model input data to a machine learning model. The method further includes processing the model input data with the machine learning model to generate model output data stored to an output record. The method further includes processing the model output data from the output record with a post processing application to generate post data stored to a post record. The method further includes generating notification data using the post data of the post record and transmitting a notification of the notification data.
