Many distributed database systems that guarantee high concurrency and scalability adopt read-write separation architecture. Simultaneously, these systems need to store massive amounts of data daily, requiring different mechanisms for storing and accessing data, such as hot and cold data access strategies. Unlike distributed storage systems, the dis...

... important index of redundancy strategy is storage efficiency, which is the ratio of original data size to redundant storage space. In Figure 7a, it can be observed that with an increasing number of table records, storage overhead based on CBase-EC was much lower than that based on three-replicas. Besides, as shown in Figure 7b we have experimented with the storage efficiency based on the change of (1 − R hot ). ...

Besides, as shown in Figure 7b we have experimented with the storage efficiency based on the change of (1 − R hot ). It can be concluded that if the CBase adopted three-replicas stores 1 PB data needed 3 PB actual storage capacity. ...

In this paper, two algorithms were introduced to describe two algorithms to describe and compare the applying of the proposed technique in the two types of the distributed database system. The First Proposed Algorithm is Homogeneous Distributed Clustering for Classification (HOMDC4C), which aim to learn a classification model from unlabeled dataset...
