SQL2003 OLAP 语法及 Cost-Base 的算法优化，让用户 就像使用关系型数据库一样使用 Hadoop。底层存储采用 HDFS， HAWQ 实现了计算节点和 HDFS 数据节点的解耦，采用 MR2.0 的 YARN 来进行资源调度，同时具有 Hadoop 的灵活伸缩的架构特性 和 MPP 的高效能计算能力。 当然，有得也有所失，虽然 HAWQ 的架构比 GreenplumMPP 数据 库灵活，但在获得架构优越性的同时，其性能比 Segment Host 之间的网络资源。 这里需要假设一下硬件指标： 主流配置，每个节点机器的磁盘 IO 性能都可达到 1GB/S 以上 (10 块 磁盘，如果 RAID 卡很优秀，甚至可以达到 2.0GB)，每个节点的网络 带宽达到 1GB/S 以上 (1 个万兆 )，CPU 主频在 2.6GHz 到 3GHz 左右， 每台机器部署 4~6 个 Primary Instance( 生产经验值 )。
