Querying Streams¶

Function¶

This API is used to query all the streams created by the current tenant.

During query, you need to specify the stream from which the stream list is returned and the maximum number of streams returned in a single request.

URI¶

GET /v2/{project_id}/streams

**Table 1** Path Parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID.

**Table 2** Query Parameters¶
Parameter	Mandatory	Type	Description
limit	No	Integer	The maximum number of DIS streams to list in a single API call Value range: 1 to 100 Default value: 10 Minimum: 1 Maximum: 100 Default: 10
start_stream_name	No	String	Name of the DIS stream to start the stream list with. The returned stream list does not contain this DIS stream name. If pagination query is required, this parameter is not transferred when you query data on the first page. If the value of has_more_streams is true, the query is performed on the next page. The value of start_stream_name is the name of the last stream in the query result of the first page.
