Deepgreen数据库基于开源MPP数据库Greenplum而来，那么他的优越性几何？今天给大家分享数据仓库测试TPC-H的结果让大家加以比较：
本次对比需要注意的几点：
- 测试参照德哥2015年发的【Greenplum的TPC-H】测试，只做了压缩类型的简单修改
- 由于测试机器性能问题，可能无法最大化展示二者性能（greenplum部分测试timeout）
一、测试环境：
服务器 IP 节点
Master 192.168.100.107 1 Master
Segment1 192.168.100.108 2 instance
Segment2 192.168.100.109 2 instance
软件版本：
Greenplum 4.3.12
Deepgreen 16.16
二、TPC-H测试结果
