Data processing method and device, electronic equipment and computer storage medium

The embodiment of the invention provides a data processing method and device, electronic equipment and a computer storage medium. The data processing method comprises steps that information of a plurality of first data blocks of a first level and information of a plurality of second data blocks of a second level which are about to be subjected to merging operation are obtained, all the data blocksof the first level have the same first size, and all the data blocks of the second level have the same second size; data comparison is conducted on each first data block and each second data block according to the information of a plurality of first data blocks and the information of a plurality of second data blocks; and according to a comparison result, data combination of the first level and the second level is conducted. The method is advantaged in that system loss caused by I/O read-write data and data comparison is effectively reduced, and the system throughput rate is improved. 本发明实施例提供了一种数据处理方法、装置、电子设备及计算机存储介
