摘要:
差异数据定位在数据增量同步等领域得到了很好的应用。 当下学者们将数据分块算法应用在差异数据定位中,提出了很多优秀的数据分块算法,并对各自算法的效率进行了论述和实验,但并没有从理论上论述数据分块算法在差异数据定位中的正确性。 此外,定位到的差异数据的大小与数据分块算法的关系也没有进行理论分析,多是以实验结果来辅助说明。 为此,文中对数据差异定位的过程进行抽象,对数据分块算法应用于该过程的正确性进行了论证,并对数据分块算法在数据差异定位中的作用进行分析。 通过理论推导的方式,证明了数据分块算法在定位差异数据时的正确性,同时得出差异数据的大小与数据分块算法的关系。 文中结论对设计应用于差异数据定位的数据分块算法有一定的参考意义。
Abstract:
Delta data location has been well applied in data incremental synchronization and other fields. At present,scholars have applieddata chunking algorithms in delta?
data location,put forward many excellent data chunking algorithms,and discussed and experimented onthe efficiency of each algorithm, but did not discuss the correctness of data chunking algorithm in delta data location theoretically.Besides,there is no theoretical analysis on the relationship between the size of the delta?
data and the data chunking algorithm,and most ofthem are only explained by the experimental results. Therefore,we abstract the process of delta data location, demonstrate the correctnessof the data chunking algorithm applied in the process and analyze the role of the data chunking algorithm in delta data location. Throughtheoretical derivation,the correctness of the data chunking algorithm in locating delta data is proved,and the relationship between the sizeof delta data and?
the data chunking algorithm is obtained. The conclusion has a certain reference significance for the design of datachunking algorithm applied to delta data location.
