The Model of Data Replica Adjust to the Need Based on HDFS Cluster
Guangbin Bao, Chaojia Yu, Hong Ping Zhao · 2012
Currently, the research on the management of data replica focuses on the management of the replica of the database data. The management of the non-database data replica is still in the initial stage. In this regard, the passage puts forward a kind of data replica model this can be adjusted dynamically according to need. The model is based on HDFS cloud storage cluster and supported by the management technology of data replica. And, through the experimental analysis, we prove that the model can improve the technology of the management of data replica of the cluster system effectively.
