An index creation method, a computing device, and a storage medium are provided. The method comprises: dividing storage records in logic sub-storage areas on the basis of the storage records and the logic sub-storage areas in a logic storage area divided in a physical storage area, the storage records comprising storage data; determining, from among multiple preset index formats according to the divided storage records, an index format matched with a record attribute; and creating a corresponding sub-index according to the determined index format to search for storage records according to the sub-index, the index format being able to cause the generated corresponding sub-index to occupy memory space smaller than a preset capacity. The index format matched with the record attribute is determined from among the multiple preset index formats, the index format can cause the generated corresponding sub-index to occupy memory space smaller than the preset capacity.

Index creation method, computing device, and storage medium

A data processing method, system and device, and a medium are provided. The method comprises: receiving a data stream; dicing the data stream to obtain a plurality of segmented data blocks; respectively calculating verification information corresponding to the plurality of segmented data blocks; and sending the segmented data blocks and the corresponding check information as a target logic block to a storage device.

Method and system, device and medium for data segmentation and check information calculation

Embodiments of the present disclosure provide a data processing method and system, a device, a storage system, and a medium. The data processing method includes: receiving a logic address corresponding to data to be processed; storing the logic address as a first access unit in a first storage pool; and in a case that the quantity of the stored first access units in the first storage pool meets a requirement, combining a plurality of first access units into a logic address group and storing the logic address group as a second access unit in a second storage pool so as to process the data based on the second access unit.
