  • MPP是大规模(Massive) 并行(Parallel) 处理(Processing) 计算架构
  • 常把运行SQL并行数据库的MPP简称为MPP.


  • SMP : 对称多处理, 多个CPU核 访问共享的内存,处理时延低,总吞吐量小
  • NUMA: 非一致性内存访问,多路CPU访问共享的内存,但CPU访问非本地内存时的时延与访问本地的不同.处理时延增加,吞吐量加大
  • MPP: 多个计算单元有各自的OS,内存,应用相互之间通过网络互连.协调计算.处理时延高,吞吐量很大.

  • 运行在MPP系统上
  • 执行数据操作(比如查询),查询可以分散到多个SQL数据库节点上.汇总后返回给用户
  • 通常并行数据库与硬件一体化提供,软件闭源,硬件也不开放.
