MongoDB as a good performance,feature-rich,supporting massive data storage products are favored by many businesses.However,because of Auto-Sharding algorithmthere which is used by MongoDB,the data on each node is uneven distributed,the CPU share is too high,there is a direct impact on system performance.Based on the research and analysis of MongoDB,we use the improved hash algorithm to optimize the program,design a distributed file system for mass data storage,and effectively address the problem of uneven distribution of data.
