Abstract: A database system is operable to perform a power supply strategy selection function based on first energy utilization-based operation optimizer input data to generate first energy utilization-based power supply strategy data denoting, for each power supply type of a plurality of power supply types, a corresponding first proportion of power supply resources that be implemented as the each power supply type. A first set of power supply resources is selected to execute a first database operation based on the first energy utilization-based power supply strategy data. The first set of power supply resources are utilized to power a first set of computing devices to enable the first set of computing devices to participate in execution of the first database operation in accordance with the first energy utilization-based power supply strategy data.

Abstract: A database system is operable to generate a query operation energy utilization estimation function based on historic energy utilization data and historic query operation execution data. A query is determined for execution and energy utilization estimation input data is determined for the query operation. The query operation energy utilization estimation function is performed upon the energy utilization estimation input data to generate energy utilization estimate data for the query operation. An energy efficiency strategy for the database system is applied based on the energy utilization estimate data generated for the query operation.

Abstract: A database system is operable to determine power usage policy data and generate operation requirement data based on the power usage policy data. A database operation is determined for execution, and an energy utilization-based operation limitation enforcement function is performed upon energy utilization-based operation restriction enforcement input data to generate energy utilization-based operation restriction enforcement data for the database operation based on applying the operation requirement data. The database operation is executed when the energy utilization-based operation restriction enforcement data indicates execution of the operation is allowed based on execution of the database operation adhering to the operation requirement data. Execution of database operation is foregone when the energy utilization-based operation restriction enforcement data indicates execution of the operation is disallowed based on execution of the database operation not adhering to the operation requirement data.

Abstract: A database system is operable to generate an energy utilization-based operation scheduling function based on power usage policy data for the database system. A storage-formatted data generation operation is determined for execution, and energy utilization-based operation scheduling input data is determined for the storage-formatted data generation operation. The storage-formatted data generation operation energy utilization-based operation scheduling function is performed upon the energy utilization-based operation scheduling input data to generate energy utilization-based operation scheduling data for the storage-formatted data generation operation. A plurality of storage-formatted data structures are generated from a plurality of records for storage based on executing the storage-formatted data generation operation in accordance with the energy utilization-based operation scheduling data.
