Problems solved by technology

Therefore, the Ceph distributed storage system is aimed at block storage applications, especially databases and other application scenarios that require high storage delays. Reducing storage costs (data compression) and IO operation delays has become a fish and bear's paw, which cannot be combined. have to

Embodiment Construction

[0058]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0059] The data compression method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the server 104 communicates with the storage system 102 through a network. The server 104 obtains the current load situation of the storage system 102, and then judges whether the current load situation meets the preset compression requirement, and if so, the server continues to judge whether the data of the object to be compressed stored in the non-compressed area is being read or written, if not If it is being read or written,...

Abstract

The invention relates to the field of data storage, in particular to a data compression method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a current load condition of a storage system; when the current load condition meets a preset compression requirement, judging whether the data of the to-be-compressed object stored in the non-compression areais being read and written or not; when the data of the to-be-compressed object is not read and written, compressing the to-be-compressed object; forbidding the data of the to-be-compressed object from being read and written when the metadata corresponding to the to-be-compressed object is processed in the compressing process, and allowing the data corresponding to the to-be-compressed object to be read and written when the data of the to-be-compressed object is compressed; and storing the compressed data to a compression area. By adopting the method, data compression and read-write operationcan be both considered.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data compression method, device, computer equipment and storage medium. Background technique [0002] The traditional Ceph distributed storage system uses BlueStore as the back-end storage module, and the data compression function is implemented in BlueStore. The native BlueStore's compression function is online compression in the usual sense, that is, the data is compressed during the write operation to the storage system, and the data is compressed and written to the storage medium after the write operation is completed. [0003] The biggest disadvantage of the above-mentioned online compression is that it has a very large impact on the delay of the write operation. After the compression function is turned on, the write operation IOPS (input and output per second (or the number of reads and writes)) of the system drops significantly. Therefore, the Ceph distr...
