Abstract

The invention provides a data transmission method and device. The data transmission method includes the steps that at least one comma separated value CSV file is pre-obtained; a leading-out instruction input by the outside is received; according to the leading-out instruction, a to-be-led-out CSV file is determined from the at least one CSV file; the data volume in the to-be-led-out CSV file is determined; according to the data volume, the to-be-led-out CSV file is divided into at least two data blocks; all the data blocks are sequentially mapped into an internal storage; the data blocks mapped into the internal storage are sequentially processed; according to the leading-out instruction, to-be-led-out data generated after processing is sent to a specified target. By means of the data transmission method and device in the technical scheme, the data processing speed of an application program can be increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method and a transmission device. Background technique [0002] With the rapid development and wide application of computer, communication and information technology, human beings are entering the information society. People all over the world can use other people's resources freely and cheaply through the establishment of networks, and realize mutual communication in different regions and at different times. However, how to transmit data quickly when sharing data has attracted more and more attention. [0003] Currently, most databases support exporting data as a comma-separated value (Comma-Separated Values, CSV) file, and then loading the exported CSV file into a cache for processing. However, when the amount of data in the CSV file is relatively large, the application program will occupy too much memory when processing the data in the CSV file, thereby ...
