Abstract
A method and device of data transmission, applied to a distributed database is provided including a plurality of nodes, with accelerator cards provided in at least two of the nodes, the high-speed interfaces of each the accelerator card is interconnected to form a data transmission path, the method including: when the accelerator card receives a database operation command from the CPU of the node requesting access to the target data, generating a data request based on the get data operation or the modify data operation; the accelerator card detects hit the target data in the cache based on the data request, the accelerator card fetches the target data from the cache; otherwise the accelerator card sends a data request message corresponding to the data request to a distant destination node via the data transmission path, and obtains the target data based on the data packet returned from the destination node.
