基于分布式FTP的二进制大对象存取算法
Binary Large Object Storage Algorithm Based on Distributed FTP
摘要
Abstract
To promote the reliability and efficiency of storing Binary Large Object ( BLOB), a new algorithm of staring BLOB data was proposed. Through the establishment of distributed BLOB storage model, the storage structure based on multiqueue waiting line was presented. It was proved that an appropriate increase in the number of waiting queues can improve system performance. The strategy of hybrid data placement was adopted, BLOB data was stored on the node of distributed FTP cluster, and BLOB data attributes was stored in the metadata server. Experimental results show that, with the constant growth of BLOB storage system capacity, each node has stable storage performance and good data integrity.关键词
