I need to model more than 1 billion time-series devices each has around 7-10 measurements in database, which cost more than 20G memory. Is there any way to reduce overhead?

CodePudding user response：

For identical devices, you can utilize the Template feature to reduce the memory overhead of Schema Management. To create, edit and set template to a device node, you can refer to interfaces in Session.
