Abstract

The invention discloses a method and a device for accelerating database operation. The invention is applied to a database connected with a hardware accelerator and the method comprises the following steps: when an initial execution plan tree which needs to be accelerated and is sent by the database is received, processing the initial execution plan tree according to basic operation and acceleration resources supported by the hardware accelerator, and forming a new execution plan tree; if the new execution cost of the new execution plan tree is smaller than the initial execution cost of the initial execution plan tree, distributing the new execution plan tree to the hardware accelerator for execution according to the organization mode and the operation mode of the hardware accelerator; and according to the execution result returned by the hardware accelerator, determining the result data after the hardware accelerator accelerates the operation of the database, so that the execution plan tree of the database is matched with the execution function and capability of the hardware accelerator for acceleration, reasonable complexity is kept, and the acceleration capability of the hardware accelerator is fully exerted.

Description

technical field [0001] The present application relates to the technical field of databases, and more specifically, to a method and device for accelerating database operations. Background technique [0002] In the past ten years, the rapid development of the mobile Internet and the digital transformation and transformation of various industries have seen large-scale data growth in various fields, but the development of general-purpose computing capabilities is facing challenges. The improvement of semiconductor technology has almost reached the physical limit. General-purpose processing Device performance can no longer grow according to Moore's Law. With the advent of 5G, cloud computing, the Internet of Everything, and the era of artificial intelligence, the requirements for data generation, transmission, storage, and analysis and processing are getting higher and higher. bigger and bigger. [0003] In the prior art, in the field of database application, under the performa...
