Aiming at the problem of low storage efficiency of small and medium files in cloud storage system based on HDFS, the paper designs a scheme of small and medium file in cloud storage System with sequential file technology. Using multidimensional attribute decision theory, the scheme by combining the indexes of reading file time, merging file time and saving memory space, we get the best way of merging small files, and can achieve the balance between the time consumed and the memory space saved; The system load forecasting algorithm based on AHP is designed to predict the system load. To achieve the goal of load balancing, the use of sequential file technology to merge small files. Experimental results show that ...
