Initialize a DIS SDK client instance named dic. For details, see Initializing a DIS SDK Client Instance.

Use the DIS SDK to obtain the information about the data cursor.

   
    
      
      //Configure the stream name.
String streamName = "myStream";
// Configure the ID of the partition for data download.
String partitionId = "0";
//Configure the sequence number for data download.
String startingSequenceNumber = "0";
//Configure the data download mode.
String cursorType = PartitionCursorTypeEnum.AT_SEQUENCE_NUMBER.name();

GetPartitionCursorRequest request = new GetPartitionCursorRequest();
request.setStreamName(streamName);
request.setPartitionId(partitionId);
request.setStartingSequenceNumber(startingSequenceNumber);
request.setCursorType(cursorType);
GetPartitionCursorResult response = dic.getPartitionCursor(request);
String cursor = response.getPartitionCursor();
