DWS轻量化更新黑科技：宽表加工优化
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 SELECT F.PERIOD_ID, F.YYYY, F.MM, F.YYYYMM, F.YYYYQ, F.QTR_NO, F.SALES_LV0_PROD_LIST_CODE, F.SALES_LV0_PROD_LIST_CN_NAME, F.SALES_LV0_PROD_LIST_EN_NAME,

从topSQL中抓取执行信息如下，看到表 dm_cbg_ci_inv_dtl_w_f_tmp_c 的宽度达到8K，加工后生成的目标表 dm_cbg_ci_inv_dtl_w_f 的宽度是9K。
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。
INSERT INTO dm_cbg_ci_inv_dtl_w_f

3.2 关联更新填充缺失字段
把非表 dm_cbg_ci_inv_dtl_w_f_tmp_c 的字段通过轻量化更新（SET enable_light_colupdate = ON）的方式更新到表 dm_cbg_ci_inv_dtl_w_f

4.扩展优化
上述step2的更新操作涉及主表dm_cbg_ci_inv_dtl_w_f和多个维表关联操作后进行更新，如果这一步耗时比较长的话，可以对这一步分拆成2个并发执行的语句进行性能加速。
