 If you have a specific connection that need to overwrite the default settings, you can create a customized section. In the previous sample, we create a specific setting named with `demo1`.  Then you can specify the configuration with option `CONF_KEY` when creating the stream definition (see [stream specs](../../../sqls/streams.md) for more info).

 如果你有个特定的源需要覆盖缺省的设置，你可以定义一个自定义的配置段。在上面的例子中，我们创建了一个新的配置 `demo1`，然后你在创建流定义的时候可以使用选项 `CONF_KEY` 来使用新的配置 (参考 [流定义规范](../../../sqls/streams.md) 获取更多详细信息)。
