Summary:The invention relates to a data difference comparison method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring source data and target data; data statistics is carried out on each piece of pipeline data of the source data and the target data, a first multi-dimensional data histogram of the source data and a second multi-dimensional data histogram of the target data are obtained, first coordinates of the first multi-dimensional data histogram and the second multi-dimensional data histogram are hash values, and second coordinates of the first multi-dimensional data histogram and the second multi-dimensional data histogram are hash values; the second coordinate is the occurrence frequency of the hash value obtained by respectively calculating each piece of pipeline data of the source data and the target data; and comparing the consistency of the first multi-dimensional data histogram and the second multi-dimensional data histogram,
