Embodiment 1
[0025] The technical solution of the present invention is realized in the following manner, a method for optimizing a file modification algorithm based on erasure code storage, the method comprising:
[0026] The data stored according to the erasure code technology will be split according to the K:M method after calculation by the algorithm, and the K data blocks and the M check blocks are objectified and stored in units of objects;
[0027] When the stored data is modified, when the modified part of the data is mapped to the corresponding data block, the object name corresponding to the data on the block can be located, that is, if the data is modified, the specific object has changed;
[0028] When the data objects are changed, the algorithm will record these changed objects, so that the data objects that have not changed can be locked and the corresponding relationship between them can be marked;
[0029] After the modified data is stored, the new object data will be writte...
Embodiment 2
[0033] As in the above embodiment, the data is stored according to the existing erasure code technology. When the data is modified, only the modified part of the data needs to be rewritten. The algorithm will reorganize the unmodified data and the newly written data. After the data reorganization is completed, it will generate New erasure check data, .
Embodiment 3
[0035] According to the above-mentioned embodiment, the data is stored according to the existing erasure code technology. When the data is modified, only the modified part of the data needs to be rewritten. The algorithm will reorganize the unmodified data and the newly written data. After the data reorganization is completed New erasure verification data will be generated.
