Save the configuration of a specific stream processing pipeline.

Prerequisites¶

A stream processing pipeline is created with the Stream Processing service, and the pipeline ID is available.

Request Format¶

POST https://{apigw-address}/streaming/v2.0/streaming/pipeline/{pipelineId}?action=save

Request Parameters (URI)¶

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description
pipelineId	Path	Mandatory	String	The stream processing pipeline ID, which can be found on the EnOS Management Console > Stream Processing > Stream Operation page. When `null` is specified, use this API to create a stream processing pipeline.
orgId	Query	Mandatory	String	The organization ID. How to get the orgId>>

Request Parameters (Body)¶

Name	Mandatory/Optional	Data Type	Description
version	Optional	String	Template version that is used by the stream processing pipeline.
name	Optional	String	Stream processing pipeline name.
templateType	Optional	Integer	Type of the template that is used by the stream processing pipeline. Possible values are 1: Origin Template; 0: Time Window Aggregation Template; 2: Multi-Merging Template; 3: Electric Energy Cal (by Metering Reading) Template; 4: Electric Energy Cal (by Average Power) Template; 5: Electric Energy Cal (by Instant Power) Template.
templateName	Optional	String	Template that is used by the stream processing pipeline.
messageChannel	Optional	Integer	Message channel that is used by the stream processing pipeline (0: real-time channel; 1: offline channel).
pipelineJson	Optional	JSONObject	Configuration of the stream processing pipeline in JSON format.

Response Parameters¶

Name	Data Type	Description
data	String	Returns the pipeline ID upon success.
