Title:
DATA TRANSFER DEVICE, DATA TRANSFER METHOD AND DATA TRANSFER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/132990
Kind Code:
A1
Abstract:
The objective of the present invention is to improve processing efficiency of partitioning and transfer processing. The present invention is provided with: a transfer destination determination unit (15) which determines a transfer destination node to be a transfer destination of data from a conversion device (2); a data reader unit (11) which reads data from a source file (17); a data transfer unit (16) which transmits the read data to a transfer destination node; a data size measurement unit (12) which measures the size of the data that has been transmitted to the transfer destination node; a partition size assessment unit (13) which assesses whether or not the size of the measured data is greater than or equal to a partition size; and a partition size setting unit (14) which, if the size of the data is assessed to be greater than or equal to the partition size and the data has been read to near the end of the source file (17), sets the value of the partition size to a value smaller than the current value. The transfer destination determination unit (15) determines the next transfer destination node if the size of the data has been assessed to be greater than or equal to the partition size.
