新增Checkpoint

参考初始化DIS客户端的操作初始化一个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。

// 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);
