曾工 您好！ 开源gp使用gpload加载数据时发现segment中数据文件大小不是始终逐渐增加，会出现回落变小最终稳定。请问这是什么原因，期间gp数据库内部做了处理？ 通过shell脚本每隔一秒中查询一次大小/data/primary/gpseg0/base/16384中文件大小，其中只有16391.6文件大小764M->869M->664M , 880M ->1.2G->940M等几次变小的情况。32M 16391.632M 16391.664M 16391.664M 16391.6128M 16391.6128M 16391.6128M 16391.6128M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6256M 16391.6284M 16391.6316M 16391.6316M 16391.6316M 16391.6316M 16391.6380M 16391.6380M 16391.6380M 16391.6380M 16391.6380M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6508M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6764M 16391.6895M 16391.6664M 16391.6664M 16391.6696M 16391.6696M 16391.6760M 16391.6760M 16391.6760M 16391.6760M 16391.6760M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.6888M 16391.61.2G 16391.61.2G 16391.61.2G 16391.61.2G 16391.61.2G 16391.61.2G 16391.61.2G 16391.6940M 16391.6940M 16391.6
