Research on the effect of compression on Hadoop performance Shanglihui, Miuli compression is an important method of I/O tuning, which reduces the I/O calculation load, thereby improving I/O performance. Today, disk I/O can never grow faster than the CPU speed of Moore's law, so I/O is often a bottleneck in data processing. In Hadoop, how to use compression for I/O tuning has not been fully studied. Through experiments, this paper draws a compression strategy to help users of Hadoop to determine when and where ...

To break the host foreign monopolies, safeguard the national information security of the Wave K relocation project, yesterday in Beijing officially launched. The "K Relocation Project" will fully accelerate shuttle K1 to replace the IOH (IBM, Oracle and HP) minicomputer process. 　　This is the first time for domestic manufacturers in the industrial core area to occupy the monopoly position of the IOH to launch a challenge. Mainframe is a high-end server dedicated to large-scale transaction data processing, and it is the core equipment of national information security. China's mainframe is faced with foreign technology monopolies and international manufacturers of market monopolies, long-term dependence on imports, this becomes our information Ann ...
