SCALABLE ACCELERATION OF DATABASE QUERY OPERATIONS

摘要

Embodiments include methods, systems and computer program products for offloading multiple processing operations to an accelerator. Aspects include receiving a database query from an application, performing an analysis on the query, and identifying a plurality of available accelerators. Aspects further include retrieving cost information for one or more templates available on each of the plurality of available accelerators, determining a query execution plan based on the cost information and the analysis on the query, and offloading one or more query operations to at least one of the plurality of accelerators based on the query execution plan.

1. A system comprising a processing device configured to:
receive a database query from an application; perform an analysis on the query; identify a plurality of available accelerators and a plurality of accelerator templates available on each of the plurality of available accelerators, wherein the plurality of accelerator templates represent different processing configurations that the accelerator is capable of executing; retrieve cost information for the plurality of accelerator templates; determine a query execution plan based on the cost information and the analysis of the query; select an accelerator template from the plurality of accelerator templates available on at least one of the plurality of available accelerators; configure the at least one of the plurality of accelerators based on the selected accelerator template; and offload one or more query operations to at least one of the plurality of accelerators based on the query execution plan.
