[TD-2309]<feature>: add config option to enable/disable stream
......@@ -95,6 +95,7 @@ TDengine系统后台服务由taosd提供,可以在配置文件taos.cfg里修
- logKeepDays:日志文件的最长保存时间。大于0时,日志文件会被重命名为taosdlog.xxx,其中xxx为日志文件最后修改的时间戳,单位为秒。默认值:0天。
- maxSQLLength:单条SQL语句允许最长限制。默认值:65380字节。
- telemetryReporting: 是否允许 TDengine 采集和上报基本使用信息,0表示不允许,1表示允许。 默认值:1。
- stream: 是否启用连续查询(流计算功能),0表示不允许,1表示允许。 默认值:1。
**注意:**对于端口,TDengine会使用从serverPort起13个连续的TCP和UDP端口号,请务必在防火墙打开。因此如果是缺省配置,需要打开从6030都6042共13个端口,而且必须TCP和UDP都打开。
