The Supervisor component has two configuration files:
supervisor.json: parameter configurations in the JSON format. This configuration file supports dynamic loading of changes and includes some important parameters in the
drc.propertiesfile.drc.properties: This configuration file has been deprecated and is reserved only for compatibility. Logic will no longer be added to this file, and existing logic in the file will no longer be modified.
Description
Notice
If a parameter is followed by a field enclosed with parentheses, this parameter replaces the field in the drc.properties file. If the parameter exists in supervisor.json and is not empty, the configuration in the supervisor.json file applies. Otherwise, the configuration in the drc.properties file applies.
