Problems solved by technology
[0002] The server core system will often send files to the downstream subsystems. If the file data volume is large, the time for the downstream subsystem to receive the delivered files, that is, the data loading time will be very long, while the server core system often Files with a large amount of data need to be delivered to multiple downstream subsystems, resulting in long overall data loading time and low efficiency
[0003] Therefore, a new technology is urgently needed to solve the problem that the overall data loading time is too long and the efficiency is very low due to the transmission of files with a large amount of data

Embodiment
[0061] see figure 1 , figure 1 It is a flowchart of a method for controlling file splitting provided by an embodiment of the present invention. like figure 1 As shown, the method includes:
[0062] Step S101, determining the number of sub-files to be split into the original file and the size of each sub-file;
[0063] Optionally, the number of sub-files that the original file needs to be split into, and the size of each sub-file are determined by technical personnel according to requirements. Wherein, the size of each sub-file can be the size of the data volume of each sub-file, or it can be that each sub-file is respectively a certain line of the previous text in the original file to a certain line of the following, such as, the original file has 5000W (ten thousand) lines, Split the original file into sub-files every 300W lines, then the first sub-file is from line 1 to line 300W, the second sub-file is from line 3000001 to line 600W, and so on.
[0064] That is to say,...

The invention discloses a file splitting control method and device. The method comprises the following steps that: determining the number of subfiles which need to be split from an original file, andthe size of each subfile; on the basis of the number of the subfiles and the size of each subfile, calculating the initial position and the final position of each subfile in the original file; recording split subfile information; on the basis of the initial position and the final position, which are obtained by calculation, of each subfile in the original file, splitting the original file, and updating the splitting state of the original file; and if the splitting state of the original file is splitting failure, starting a breakpoint continuous splitting operation. By use of the technical scheme provided by the invention, the file (i.e., the original file) with a large data size can be split, the data size of the single split subfile becomes small, the data loading time of all split subfiles is extremely shorter than the data loading time of the original file so as to be favorable for subsequent data loading, integral data loading time is effectively shortened, and efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of file processing, in particular to a file split control method and device. Background technique [0002] The server core system will often send files to downstream subsystems. If the amount of data in the distributed files is large, the time for the downstream subsystem to receive the distributed files, that is, the time for data loading, will be very long, while the server core system often Files with a large amount of data need to be delivered to multiple downstream subsystems, resulting in long overall data loading time and low efficiency. [0003] Therefore, there is an urgent need for a new technology to solve the problems that the overall data loading time is too long and the efficiency is very low due to the transmission of files with a large amount of data. Contents of the invention [0004] In view of this, the present invention provides a file splitting control method and device, which can spl...
