Abstract

The invention discloses a data transmission method and device, which are applied to a distributed database including a plurality of nodes. At least two nodes are provided with acceleration cards, and the high-speed interfaces of the acceleration cards are connected to each other to form a data transmission path. The method includes: : When the accelerator card receives a database operation instruction issued by the node's CPU to obtain the target data, it generates a data request according to the data acquisition operation or the data modification operation; if the accelerator card detects the hit target data in the cache according to the data request, the accelerator card Obtain the target data from the cache; otherwise, the accelerator card will send the data request message corresponding to the data request to the remote destination node through the data transmission path, and obtain the target data based on the data packet returned from the destination node, thereby reducing the cross-sectional area. The communication delay between accelerator cards of nodes.

Description

technical field [0001] The present application relates to the technical field of databases, and more particularly, to a data transmission method and apparatus. Background technique [0002] With the advent of the era of 5G, cloud computing, the Internet of Everything and artificial intelligence, the requirements for data generation, transmission, storage, and analysis and processing are getting higher and higher. In the database field, the large amount of data in the integration of lakes and warehouses is accompanied by new requirements for system performance, scalability and cost. Distributed database is a key solution. At the same time, in the node, acceleration cards such as GPU (graphics processing unit, graphics processor), FPGA (Field Programmable Gate Array, field programmable gate array) or customized ASIC (Application Specific Integrated Circuit, application-specific integrated circuit) chips are used. Key processing steps in the database are implemented through sp...
