+## 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
