本文分享自华为云社区《GaussDB(DWS)性能调优：宽表加工优化方案》，作者：譡里个檔 。
1. 业务背景
宽表加工性能慢，在Gauss(DWS)中可以使用DWS的轻量化更新的黑科技实现性能成倍提升
2. 原始逻辑
事实表和维表关联之后插入目标表 dm_cbg_ci_inv_dtl_w_f
INSERT INTO dm_cbg_ci_inv_dtl_w_f

3. 优化逻辑
3.1 源表字段写入目标表
把表 dm_cbg_ci_inv_dtl_w_f_tmp_c 的数据先导入目标表 dm_cbg_ci_inv_dtl_w_f，对于来源不是表 dm_cbg_ci_inv_dtl_w_f_tmp_c 的字段先置为NULL。
