The security group of the ECS must be the same as that of the master node in an MRS cluster. The ECS and the MRS cluster must be in the same VPC. The ECS network interface controller (NIC) and the MRS cluster must be in the same network segment.

Table 3 describes the main configuration files (Obtain required files as required).
ROOT is a root node, and each node at the sensor layer is a leaf node. According to the IoTDB syntax, the path from ROOT to a leaf node is separated by a dot (.). The complete path is used to name a time series in the IoTDB.
