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

[0041] 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.

[0042] 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 invention discloses a compression method, system and equipment and a computer readable storage medium. The method comprises the steps that the service pressure of a compression process in storageequipment at the current moment is acquired; judging whether to compress the newly received to-be-stored data or not based on the service pressure; if yes, calling a compression process to compress and store the to-be-stored data; and if not, directly storing the to-be-stored data. The invention discloses a compression method. judging whether to compress the to-be-stored data or not according to the service pressure of the compression process; namely, the compression method provided by the invention selectively compresses the to-be-stored data according to the service pressure of the compression process, so that the storage equipment can reduce the load pressure caused by data compression, reduce the risk of IO blockage, improve the IOPS of the storage equipment and improve the performanceof the storage equipment. The compression system and equipment and the computer readable storage medium disclosed by the invention also solve the 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...
