GP 6总体架构学习笔记

- Master、Secondary 、Segment、Mirror都是pg实例
- 注意gp使用的pg有一定定制化的
- 实例间数据复制通过WAL日志模式实现
- 同一份数据的Mirror和Segment应该错开部署,避免在同一物理机器上
- 大规模数据导入、导出建议都通过外部表,而非copy模式 (Greenplum管理员指南6.2.1.pdf)提到copy都会通过master
- Secondary默认应该单独部署并且无其它任何任务以保障master出现问题后的快速切换
边栏推荐
- mongo enters error
- Browser's built-in color picker
- Small program: Matlab solves differential equations "recommended collection"
- 全新宝马3系上市,安全、舒适一个不落
- The principle of hough transform detection of straight lines (opencv hough straight line detection)
- arm按键控制led灯闪烁(嵌入式按键实验报告)
- Single-cell sequencing workflow (single-cell RNA sequencing)
