- 测试结果
本文档描述xxxx测试中6个典型测试场景的测试结果及背景，旨在对不同数据量，不同存储方式，不同优化器三者的组合优化进行探索，进而为未来的类似测试提供组合优化参考。
| 数据插入（500万） | 5进程批量插入（500万） | 单表增量与数据合并去重（1000万） | 简单查询（3亿数据） | 综合统计（3亿数据） | 排序过滤（3亿数据） | |
| xxx | 18s | 25s | 28s | 0.049s | 41s | 144s |
| 金仓 | 31.808s | 36.998s | 19.888s | 0.463s | 8.496s | 37.311s |
经测试发现在目前的测试数据量和计算实例部署的情况下，大多数场景使用pg优化器+heap表+索引的方式得到比AO表+9级zlib压缩+GPORA的组合更好的测试结果。
在简单查询模式测试（三个in查询子嵌套）的测试场景，使用heap表+索引+GPORCA得到比pg优化器更好的测试结果
思考：选用heap或者ao表和数据量，部署的计算实例及查询语句条件相关，目前没有探索到一个选择定量标准，需要在更多的测试环境中验证

- 测试场景及SQL
测试共6个场景，各个场景sql如下（后缀’_c’表示列存表，‘_r’表示行存表,’_p’为分区表），除特别注明默认优化器使用pg
- 批量数据插入测试
INSERT INTO tb_mz_sfmxb_500_c select * from tb_mz_sfmxb_source_r limit 5000000;
- 多进程批量数据插入测试
INSERT INTO CENYLFW.tb_mz_sfmxb_500_bf_r select * from CENYLFW.tb_mz_sfmxb_source_r limit 5000000;
- 单表增量数据与历史数据去重合并测试
