Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. The token can be obtained by calling the IAM API (value of X-Subject-Token in the response header).

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
destination_type	Yes	String	Dump destination. Possible values: OBS: Data is dumped to OBS. Default: NOWHERE Enumeration values: OBS
obs_destination_descriptor	No	OBSDestinationDescriptorRequest object	Parameter list of OBS to which data in the DIS stream will be dumped.

**Table 4** OBSDestinationDescriptorRequest
Parameter	Mandatory	Type	Description
task_name	Yes	String	Name of the dump task. The task name consists of letters, digits, hyphens (-), and underscores (_). It must be a string of 1 to 64 characters.
agency_name	Yes	String	Name of the agency created on IAM. DIS uses an agency to access your specified resources. The parameters for creating an agency are as follows: Agency Type: Cloud service Cloud Service: DIS Validity Period: unlimited Scope: Global service, Project: OBS. Select the Tenant Administrator role for the global service project. If agencies have been created, you can obtain available agencies from the agency list by using the "Listing Agencies " API. This parameter cannot be left blank and the parameter value cannot exceed 64 characters. If there are dump tasks on the console, the system displays a message indicating that an agency will be automatically created. The name of the automatically created agency is dis_admin_agency. Maximum: 64
deliver_time_interval	Yes	Integer	User-defined interval at which data is imported from the current DIS stream into OBS. If no data is pushed to the DIS stream during the current interval, no dump file package will be generated. Value range: 30-900 Default value: 300 Unit: second Minimum: 30 Maximum: 900 Default: 300
consumer_strategy	No	String	Offset. LATEST: Maximum offset, indicating that the latest data will be extracted. TRIM_HORIZON: Minimum offset, indicating that the earliest data will be extracted. Default value: LATEST Default: LATEST Enumeration values: LATEST TRIM_HORIZON
file_prefix	No	String	Directory to store files that will be dumped to OBS. Different directory levels are separated by slashes (/) and cannot start with slashes. The value can contain a maximum of 50 characters, including letters, digits, underscores (_), and slashes (/). This parameter is left empty by default. Maximum: 50
partition_format	No	String	Directory structure of the object file written into OBS. The directory structure is in the format of yyyy/MM/dd/HH/mm (time at which the dump task was created). N/A: Leave this parameter empty, indicating that the date and time directory is not used. yyyy: year yyyy/MM: year/month yyyy/MM/dd: year/month/day yyyy/MM/dd/HH: year/month/day/hour yyyy/MM/dd/HH/mm: year/month/day/hour/minute Example: in 2017/11/10/14/49, the directory structure is 2017 > 11 > 10 > 14 > 49. 2017 indicates the outermost folder. Default value: empty. Note: After data is successfully dumped, the directory structure is obs_bucket_path/file_prefix/partition_format. Enumeration values: yyyy yyyy/MM yyyy/MM/dd yyyy/MM/dd/HH yyyy/MM/dd/HH/mm
obs_bucket_path	Yes	String	Name of the OBS bucket used to store data from the DIS stream.
destination_file_type	No	String	Dump file format. Possible values: Text (default) Default: text Enumeration values: text
processing_schema	No	ProcessingSchema object	Dump time directory generated based on the timestamp of the source data and the configured partition_format. Directory structure of the object file written into OBS. The directory structure is in the format of yyyy/MM/dd/HH/mm.
record_delimiter	No	String	Delimiter for the dump file, which is used to separate the user data that is written into the dump file. Value range: Comma (,), which is the default value Semicolon (;) Vertical bar (\|) Newline character (\n) Default: \n

**Table 5** ProcessingSchema
Parameter	Mandatory	Type	Description
timestamp_name	Yes	String	Attribute name of the source data timestamp.
timestamp_type	Yes	String	Type of the source data timestamp. String Timestamp: 13-bit timestamp of the long type
timestamp_format	No	String	OBS directory generated based on the timestamp format. This parameter is mandatory when the timestamp type of the source data is String. Value range: yyyy/MM/dd HH:mm:ss MM/dd/yyyy HH:mm:ss dd/MM/yyyy HH:mm:ss yyyy-MM-dd HH:mm:ss MM-dd-yyyy HH:mm:ss dd-MM-yyyy HH:mm:ss Enumeration values: yyyy/MM/dd HH:mm:ss MM/dd/yyyy HH:mm:ss dd/MM/yyyy HH:mm:ss yyyy-MM-dd HH:mm:ss MM-dd-yyyy HH:mm:ss dd-MM-yyyy HH:mm:ss
