Graph mining is widely used in fields like social network analysis. The synchronous vertex-centric frameworks strike better balance between the performance and ease-of-use, so they are widely used in realistic. However, traditional architectures of this type, like the vertex-based push architecture and GAS, are encumbered by high communication costs. In this paper we proposed a new replica-based push...
Hadoop is a popular open-source framework that allows distributed analysis of large datasets using the MapReduce programming model. A distributed file system HDFS is implemented to provide high-throughput access to datasets. HDFS can achieve high performance metadata service but has two disadvantages. First, when the metadata server stores metadata on persistent devices, it is restricted to read and...
As application requirements increase in quantity and popularity, big data storage is becoming an important technology which data centers and Internet companies depend on. The cluster file system with centralized metadata management often encounters planned or unplanned downtime which requires higher reliability for metadata service. Current paradigms use the backup server to take over as the primary...
To store and manage data efficiently is the critical issue which modern information infrastructures confront with. To accommodate the massive scale of data in the Internet environment, most common solutions utilize distributed file systems. However there still exist disadvantages preventing these systems from delivering satisfying performance. In this paper, we present a Name Node cluster file system...
