Step 3: Sending Data to DIS
Function
Local data is continuously uploaded to DIS.
NOTE:
Data can be stored in MRS, DIS, OBS, and DLI. For how to configure a storage location, see Creating a Dump Task.
The maximum number of days for DIS to preserve data cannot exceed Data Retention (days).
Sample Code
The example code file is the ProducerDemo.java file in the \dis-sdk-demo\src\main\java\com\bigdata\dis\sdk\demo directory decompressed from the huaweicloud-sdk-dis-java-X.X.X.zip package. The compression package is downloaded from the DIS SDK.
Running the Producer Program
Right-click the producer application and choose Run As > 1 Java Application from the shortcut menu.

While data is being sent to DIS, the DIS console displays DIS stream information. If information similar to the following is displayed, the data has been successfully sent to DIS:
