# 新增Checkpoint
参考[初始化DIS客户端](https://support.huaweicloud.com/sdkreference-dis/dis_06_0015.html)的操作初始化一个DIS客户端实例，实例名称为dic。
使用DIS SDK创建Checkpoint，需要指定通道名称、APP名称、分区编号、序列号以及Checkpoint类型。
其中，"streamName"的配置值要与[开通DIS通道](https://support.huaweicloud.com/usermanual-dis/dis_01_0601.html)中"Stream Name"的值一致。
```
// 通道名称 
String streamName = "myStream"; 
// APP名称
String appName = "myApp";
CommitCheckpointRequest commitCheckpointRequest = new CommitCheckpointRequest();
commitCheckpointRequest.setStreamName(streamName);
commitCheckpointRequest.setAppName(appName);
// 需要提交的sequenceNumber
commitCheckpointRequest.setSequenceNumber("100");
// 分区编号
commitCheckpointRequest.setPartitionId("0");
// Checkpoint类型
commitCheckpointRequest.setCheckpointType(CheckpointTypeEnum.LAST_READ.name());
```
配置"CommitCheckpointRequest"对象之后，通过调用 commitCheckpoint 提交checkpoint。
```
dic.commitCheckpoint(commitCheckpointRequest);
```
