Problems solved by technology

[0003] However, in the process of compressing the data to be stored, compressing the data to be stored will increase the CPU load, and the data to be stored is stored by the IO process, so when the data to be stored is compressed, the IO will sometimes be blocked, affecting the IOPS of the device (Input / Output Operations Per Second, the number of read and write operations per second), which reduces the performance of the storage device

Embodiment Construction

[0040] 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.

[0041] In the storage field, there are various kinds of data to be stored, and the requirements for high load and low latency of storage devices are getting higher and higher. In order to save the space of the storage device, when storing the data to be stored, the data to be stored will be compressed. However, in the process of compressing the data to be stored, compressing the data to be stored will increase the CPU load, and the data to be stored is stored by the IO process, so w...

Abstract

The present application discloses a compression method, system, device, and computer-readable storage medium. The method includes: acquiring the compression rate of the compressed data in the storage device in the current judgment cycle; The data to be stored is compressed; if yes, the data to be stored is compressed and stored; if not, the data to be stored is directly stored. A compression method disclosed in the present application judges whether to compress the data to be stored according to the compression rate of the compressed data, so that the storage device can reduce the load pressure caused by the compressed data, reduce the risk of IO blocking, and improve the storage efficiency. The IOPS of the device improves the performance of the storage device. A compression system, device, and computer-readable storage medium disclosed in the present application also solve corresponding technical problems.

Description

technical field [0001] The present application relates to the field of storage technologies, and more specifically, to a compression method, system, device, and computer-readable storage medium. Background technique [0002] In the storage field, there are various kinds of data to be stored, and the requirements for high load and low latency of storage devices are getting higher and higher. In order to save the space of the storage device, when storing the data to be stored, the data to be stored will be compressed. [0003] However, in the process of compressing the data to be stored, compressing the data to be stored will increase the CPU load, and the data to be stored is stored by the IO process, so when the data to be stored is compressed, the IO will sometimes be blocked, affecting the IOPS of the device (Input / Output Operations Per Second, the number of read and write operations per second), which reduces the performance of the storage device. [0004] To sum up, ho...
