思源版本 2.2.3
粘贴以下内容，删除 ~~~ 后撤销，出现状态异常；
我们也可以通过自定义分区规则和分区个数，来控制数据按业务规则聚集。具体操作实现如下：
- 自定义类继承Partitioner，重写getPartition()方法
~~~java
public class MyPartitioner extends Partitioner<K, V> {
@Override
public int getPartition(K key, V value, int numPartitions) {
int partition = 0;
//分区的编号规则为从0开始的自然数流水序列
return partition;
}
}
~~~
操作过程：
- 直接 ctrl+v 粘贴
- 删除
~~~java前的~直到删除换行 - ctrl+z 撤销
