Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0056] At present, when the storage space is released by erasing blocks in the prior art, the amount of data migration and writing is relatively large, which will increase the wear of the storage medium and reduce the lifespan and performance of the storage medium. To this end, the present application provides a data processing solution, which can reduce the wear of the storage medium and improve the lifespan and performance of the storage medium.

[0057] see figure 1 As shown, th...

Abstract

The invention discloses a data processing method and device, equipment and a readable storage medium. The method disclosed by the invention comprises the following steps: receiving a garbage collection instruction; determining a physical data page corresponding to the garbage collection instruction; querying a logic address corresponding to the physical data page; increasing the updating period of the logic address to obtain a target updating period, wherein the updating period represents the activeness of the data in the physical data page; calculating the difference degree between the target updating period and the preset period of each group; and migrating data in the physical data page to the physical block corresponding to the group corresponding to the minimum difference degree. The cold and hot data can be stored separately, the abrasion of the storage medium is reduced, and the service life of the storage medium is prolonged, and the performance of the storage medium are improved. Correspondingly, the invention also discloses a data processing device and equipment and a readable storage medium, which also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, equipment and readable storage medium. Background technique [0002] In solid-state hard disks and Nand Flash storage media, garbage collection can be used to release the space occupied by invalid data pages, so as to realize the recovery of available space. Among them, the garbage collection operation is to erase the block, and the erase block will bring about the migration of valid data pages. When there are many valid data pages, it will lead to an increase in the amount of data written (that is, write amplification), and the increase in the amount of data written will cause Accelerate the wear of the storage medium and reduce the life and performance of the storage medium. [0003] Taking a solid state disk as an example, the solid state disk includes multiple physical blocks, and each physical block includes multiple data pa...
