Description

Bug Description topic订阅的数据会出现脏数据

To Reproduce 我是用telegraf采集数据,然后TD接收数据,之前是用的3.0.4版本,没出问题,后面由于环境问题升级到3.2.2.0,然后就出现这个问题, 数据订阅的数据会获取到很多不存在表里的数据,然后有些存在表里的数据,数据订阅无法获取到

Screenshots 下面图片分别是数据库的数据和数据订阅后打印出来的数据: image image

Environment (please complete the following information):

  • OS: CentOS 7.0
  • Memory, CPU, current Disk Space
  • TDengine Version: 3.2.2.0
