On May 16th doctor Bian Haoqiong presented the thesis entitled “Wide Table Layout Optimization based on Column Ordering and Duplication” and had interactions and communications with the participants. This thesis is the fruit of the corporation our school made with MSRA and doctor Bian Haoqiong was the first author, other writers included associate professor Chen yueguo and professor Du Xiaoyong. The thesis improved the access performance on the wide table data of HDFS(Hadoop Distributed File System) through adjusting data columns and copying commonly used columns in column-based storage in HDFS. HDFS is the common platform and industrial standard, and the improving of its data storage and access performance has vast importance to the mass data ecosystem.
