Abstract

The invention discloses a method and device for implementing direct erasure correction. The method includes: receiving a request operation sent by a client, and performing preprocessing on the request operation; The request operation of fetching the source data is stored in the read list, and the request operation that does not need to read the source data is put into the write list; for the request operation of the write list, the request operation of the write list is directly stored in the memory Execute in; for the request operation in the read list, analyze the request operation in the read list, execute the request operation in the read list in memory; combine the write list and the read list All request operations are merged in the memory, the merged request operations are generated into corresponding transactions, and the transactions are placed on disk. The method realizes improving the read-write efficiency of data and solves the bottleneck problem of data capacity.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for realizing direct erasure correction. Background technique [0002] At present, with the rapid development of computer technology, data is growing explosively; the security of data storage in cloud storage systems and the utilization of disks are getting more and more attention. Generally, in cloud storage systems, there is a cache cache pool at the front end of the erasure code, and the data is first written into the cache cache. After certain conditions are met, the data will be transferred from the cache cache pool to the erasure pool; instead of data being written When entering, it is directly written into the erasure pool. At present, erasure codes in cloud storage systems are generally only positioned for cold data storage, and important data is stored in multiple copies. [0003] The above process is the process of indirect erasure correction....
