The algorithm of file backup and distribution dynamic adjustment in Telecom data Warehouse based on cloud platform

Dynamic adjustment algorithm of file backup and distribution in telecom data Warehouse based on cloud platform Yang Miaomiao Li-Liu Jinghu Hadoop leverages a unified backup mechanism to ensure data availability and fault tolerance. However, for important blocks of files, you can only set the number of replicas by modifying the configuration file. By analyzing the access situation of data Warehouse files in telecom industry, this paper proposes a dynamic adjustment algorithm (BPDA) for file backup and storage to improve the data locality, so as to reduce the I/O and network consumption caused by data transmission, and to improve query efficiency. Using a multiple replica consistency hashing algorithm, probabilistic sampling and competitive weakening ...
