如题**qidaijie** commented on *2023-10-20T11:53:10.441+0800*:
环境背景:
* PoC环境为TSG OLAP与CN OLAP在相同物理服务器上分虚拟机混部CPU/内存资源隔离共用IO资源。
* OLAP计算程序数据库等均混部在虚拟机上。
高峰期整点查询较慢的原因为:
* TSG OLAP整点会调用IP Learning离线程序该程序会基于过去1小时的session日志进行学习。
* TSG OLAP Druid程序整点会将过去1小时的数据落盘并重新构建实时任务。
 
上述会影响服务器资源,尤在流量高峰期(日志量6w/s流量平稳期2.5w/s)时数据入库会占用较多磁盘IO故查询时间与日志量、资源等呈相关关系。
 
后续讨论:
# PoC等环境服务器规划时对IO密集型、CPU密集型组件进行物理隔离尽可能避免由于混部带来的资源抢占。
# 对任务调用方式和周期进行讨论,减少在某点集中调用使用大量的资源的问题。
