+## 多数据源示例
+
+单数据源，从多个 MySQL 读取数据同步到 Doris 的 Pipeline 可以定义如下：
+
+```yaml
+source:
+ type: mysql_mutiple
Review Comment:
> ```yaml
> sources:
> - type: mysql
> name: mysql-instance-00
> hostname: localhost
> port: 3306
> ....
> - type: mysql
> name: mysql-instance-01
> hostname: localhost
> port: 3307
> ....
> ```
>
> And the corresponding PipelineDef looks like this:
>
> ```java
> public class PipelineDef {
> @Nullable private List<SourceDef> sources;
> private final SourceDef source;
> ...
> }
> ```
>
> If the `sources` is not null then we use these data sources, otherwise we
use `source` to build up DataStream. In this way, the previous usage will not
be affected. I want to hear your opinion. @yuxiqian @ChaomingZhangCN
