Abstract
A method and device for accelerating database operation, applied to a database connected with a hardware accelerator is provided, the method includes: when receiving an initial execution plan tree sent by the database that needs to be accelerated, processing the initial execution plan tree and generating a new execution plan tree and a new execution cost based on the basic operation and accelerated resource supported by the hardware accelerator; if the new execution cost of the new execution plan tree is less than the initial execution cost of the initial execution plan tree, distributing the new execution plan tree to the hardware accelerator for execution based on the organization approach and the operation approach of the hardware accelerator; the execution result returned by the hardware accelerator to complete the accelerated operation of the database operation; determining the result data after the hardware accelerator accelerates the database operation based on the execution results returned by the hardware accelerator, so that the execution plan tree of the database matches the execution function and capability of the hardware accelerator that performs the acceleration and maintains a reasonable complexity.
