PRESCRIPTIVE ANALYTICS BASED NOSQL DATABASE SERVICE OPTIMIZATION SYSTEM FOR CLOUD COMPUTING

摘要

A system includes a multi-layer throughput optimization (TPO) stack to generate a token containing prescriptions for rightsizing database service throughput. A prescriptive engine layer of the TPO stack may obtain consumed throughputs from the utilization tracking data; predict, based on the consumed throughputs, a prediction-based throughput for the target NoSQL database service; select target consumed throughputs from the consumed throughputs based on a time granularity; determine a statistical throughput consumption value from the target consumed throughputs; calculate a statistics-based throughput over a TPO interval based on the statistical throughput consumption value; extract database service performance metric data from the utilization tracking data; select target performance metric data from the database service performance metric data based on the time granularity; determine a statistical performance metric value from the target performance metric data; select one of the prediction-based throughput and the statistics-based throughput as based on the statistical performance metric value.
