Updating a Dump Task

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

When using the DIS SDK to update a dump task, you need to specify the stream name, dump task name, dump interval, and dump destination.

//Configure global parameters of the dump task. A single-parameter update is not supported.
UpdateTransferTaskRequest request = new UpdateTransferTaskRequest();

//Configure the name of the stream to which the dump task to be updated belongs.
request.setStreamName(streamName);

//Configure the name of the dump task to be updated.
OBSDestinationDescriptorRequest descriptor = new OBSDestinationDescriptorRequest();
descriptor.setTransferTaskName(taskName);

//Configure the OBS bucket name and folder name. You can create OBS buckets and files on the OBS console or client.
descriptor.setObsBucketPath("obs-dis1");
descriptor.setFilePrefix("transfertask");

//Configure the dump interval that is expressed in units of seconds.
descriptor.setDeliverTimeInterval(300);

//(Optional) Configure the dump file format. By default, the value is Text. Other available options are Parquet and CarbonData.
descriptor.setDestinationFileType(DestinationFileTypeEnum.TEXT.getType());

request.setObsDestinationDescriptor(descriptor);

After configuring UpdateTransferTaskRequest, you can call the updateTransferTask method to update the dump task.
