Modifying Parameters of GeminiDB Influx Instances

You can modify parameters in a custom parameter template so that your instance can deliver spectacular performance.

Note that parameter values in default parameter templates cannot be changed.

  • Exercise caution when modifying parameter values to prevent exceptions.
  • Though parameter values in a default template cannot be changed, you can view details about a default parameter template. If a custom parameter template is set incorrectly, the database startup may fail. You can re-configure the custom parameter template according to the configurations of the default parameter template.
