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。
1 2 3 4 5 6 7 8 9 10 11 12 13 |
// 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);
