Abstract
The disclosure discloses a method and system for reducing an amount of data transfer in data synchronization, in which the method comprises: identifying different data values in each data column within a changed source data table; coding data values in each data column, wherein, for each data column, different data values have different coding values; identifying different ChangeType and ChangeBits in data change history information; and generating a change matrix by using the coding values of different data values in each data column according to different ChangeType and ChangeBits. With the change matrix, data having the same change for different rows within an initial data change are merged into a same change row within the change matrix, thereby reducing amount of data transfer and improving synchronization efficiency.
