Problems solved by technology

Therefore, when the EC-based redundancy technology writes and reads data, the redundancy of the copy is too large
[0009] More importantly, simply increasing the number of K and M will undoubtedly increase the IO delay, and seriously affect the IO performance of CEPH or other types of distributed storage systems, and cause a very large impact on the CPU and memory of the computer. Computational overhead and a huge waste of disk storage space

Abstract

The invention provides a data processing method based on a distributed storage system. The method comprises the following steps: defining a compressed configuration item that comprises at least a compression mode, off-line compression start time and off-line compression termination time; when to-be-processed data is written in, using a client or a server, or the client and the server to successively perform chain type compression processing on the to-be-processed data, and determining the time of the server intervening to perform the chain type compression processing only in the off-line compression mode according to the off-line compression start time and the off-line compression termination time; when the to-be-processed data is read, at least enabling the client to perform chain type decompression processing; after the chain type compression processing or the chain type decompression processing is performed, responding to an opposite end device through a network. After the data processing method based on the distributed storage system is used, the bandwidth utilization rate is increased, the memory space is saved, the data reconstruction speed is accelerated, and the data handling capacity of the distributed storage system is improved when a write operation or read operation is performed.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a data processing method based on a distributed storage system. Background technique [0002] With the development of virtualization, cloud computing and big data, distributed storage systems have become the main way of data storage. In the field of open source distributed storage, distributed storage systems have adopted copy-based redundancy technology or EC technology. [0003] CEPH is an open source unified distributed storage system and one of the most mainstream open source storage projects mentioned above. CEPH is implemented based on the C / S (client / server) architecture. The client can provide external object access interfaces through RADOS, and can also provide high-level application interfaces on top of RADOS. The high-level application interfaces include RBD, RGW and Ceph FS; the server Including OSD, MON and MDS, responsible for data storage, CEPH cluster...
