Set Config Action

    Query parameters

    • persist

      Whether to persist the modified configuration. The default is false, which means it is not persisted. If it is true, the modified configuration item will be written into the file and will still take effect after FE is restarted.

    • reset_persist Whether or not to clear the original persist configuration only takes effect when the persist parameter is true. For compatibility with the original version, reset_persist defaults to true.
      If persist is set to true and reset_persist is not set or reset_persist is true, the configuration in the fe_custom.conf file will be cleared before this modified configuration is written to fe_custom.conf.
      If persist is set to true and reset_persist is false, this modified configuration item will be incrementally added to fe_custom.conf.

    Response

    The field indicates the successfully set configuration. The err field indicates the configuration that failed to be set. The persist field indicates persistent information.
