A database system includes a query and response sub-system including a computing device cluster of pluralities of computing device clusters that includes a plurality of computing devices where a first computing device of the plurality of computing devices includes a plurality of computing nodes. A first computing node includes a first plurality of processing core resources of pluralities of processing core resources of the database system. A set of computing nodes is operable to obtain a query that includes an optimized K means model generation operation, determine K means model parameters, generate a query execution plan based on the optimized K means model generation operation and the K means model parameters, and provide corresponding portions of the query execution plan to corresponding processing core resources of the pluralities of processing core resources to execute the query execution plan and store a generated K means model.
