Problems solved by technology

In the direct erasure code of the cloud storage system, the front-end cache pool is canceled. The principle of implementation is to read the source data into the memory first, and then apply all the operations in the queue to the source data in the memory. After the operation application is completed, Finally, complete overwriting is performed, and there is a case where data is repeatedly written.

Abstract

The invention discloses a direct erasure code optimization method based on cloud storage. The method comprises the steps of: receiving an operation sent by a client, judging whether the operation is an accurate operation, and if so, writing the operation into a queue; traversing all operations in the queue, recording data scope information of the operations, and respectively merging the operations and the data scope information; judging whether the merged operation is an alignment operation according to the merged data scope information, and if so, generating an alignment operation affair; and submitting the alignment operation affair to a cloud storage system for data disk storage, thus completing data writing. According to the direct erasure code optimization method based on cloud storage, the operations in the queue are traversed, the data scope information of the operations is recorded, the operations and the data scope information are respectively merged, and a plurality of operations can be processed at one time by merging the operations, so that the processing efficiency is improved, rewrite of data is avoided, and the data writing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, and more specifically, relates to a cloud storage-based direct erasure code optimization method, and also relates to a cloud storage-based direct erasure code optimization system. Background technique [0002] Today, with the rapid development of computer technology, data is growing explosively, and the speed of data storage in cloud storage systems has attracted more and more attention. Among them, erasure codes have received more and more attention as the main method of fault tolerance in storage systems. [0003] There is a buffer pool at the front end of the erasure code. Data is first written into the buffer pool. After certain conditions are met, the data will be transferred from the buffer pool to the erasure pool instead of being directly written into the erasure pool when there is data written. In the direct erasure code of the cloud storage system, the front-end cache pool...
