业务场景:查询出亿级明细数据结果集(不分页),提交给算法引擎
当前问题:查询时间久,无法获取返回结果
查询语句:select business_time,ref_value from reftable where business_time>='2020-01-01 00:00:00' and business_time< '2021-01-01 00:00:00' and ref_value=1
语句释义:一年数据量大概有一亿五千万,需要将一亿五千万数据全部从reftable获取到后一次性提交给算法引擎服务,reftable以bussiness_time按月分区,以ref_value自动分桶(doris1.2)

机器配置:128核CPU,256内存,100T硬盘arm架构服务器五台(保密单位,无法提供图片和文件,请谅解)
