Compass support a config option to force connection options to have a specific value. These options can then not be overridden through the connection form or by specifying them in the connection string. These options can be specified on the command line, or in the global config file. Example global config file section (YAML): forceConnectionOptions: - readPreference: secondary - readPreferenceTags: nodeType:ANALYTICS - readPreferenceTags: nodeType:READ_ONLY Example global config file section (JSON): "forceConnectionOptions": [ ["readPreference", "secondary"], ["readPreferenceTags", "nodeType:ANALYTICS"], ["readPreferenceTags", "nodeType:READ_ONLY"] ] Example command line specification: --forceConnectionOptions.readPreference=secondary --forceConnectionOptions.readPreferenceTags=nodeType:ANALYTICS --forceConnectionOptions.readPreferenceTags=nodeType:READ_ONLY (picking this example to show how to specify an option that can be specified more than once)
