DATA PROCESSING METHOD, APPARATUS, ELECTRONIC DEVICE, AND COMPUTER STORAGE MEDIUM

A data processing method including: acquiring information of multiple first data blocks of a first level to be merged and information of multiple second data blocks of a second level to be merged, wherein each of the first data blocks of the first level has the same first size, and each of the second data blocks of the second level has the same second size; performing, according to the information of the multiple first data blocks and the information of the multiple second data blocks, data comparison on each of the first data blocks and each of the second data blocks; and performing, according to a comparison result, data compaction on the first level and the second level. The embodiments of the present disclosure effectively reduce system overheads caused by I/O data read and write and data comparison, thereby improving the system throughput.
