[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] In the existing data reading and writing method based on index sorting, each time new data is written, the data block occupied by the written data needs to be moved back in the memory, resulting in a lot of kernel resource consumption. In the embodiment of the present invention, considering the improvement of the existing index structure, the method of quick sorting of the secondary index is adopted, that is, the technology of the secondary index cache is adopted to perform detailed control of the micro-group index in chronological order to form multiple stores The secondary index of the data block address ID information of the written data, so that when the data block corresponding to one of the secondary indexes is written, the d...
