View processing node details¶

Read the configuration and running snapshot of a product-related processing node.

HTTP
GET $CLOUDSIGMA_API_BASE/lineage/artifacts/{artifact_id}/nodes/{node_id}

Before you call this API¶

Configure the regional API endpoint and authentication, and select the target workspace.

First query the product processing link, and obtain the product ID and node ID from the response.

The node ID cannot be replaced by the node display name.

Request¶

Input examples

Shell
curl "$CLOUDSIGMA_API_BASE/lineage/artifacts/$ARTIFACT_ID/nodes/$NODE_ID" \
  -H "X-API-Key: $CLOUDSIGMA_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID"

Parameter reference

Request parameters

Parameter	Type	Required	Description
`artifact_id`	string	Required	Processing result ID, taken from data.artifact.artifact_id in processing result lineage.
`node_id`	string	Required	Node ID in the processing topology, taken from data.topology.producer_node_id or data.topology.nodes[].node_id.

Successful response¶

data returns the node identity, selected run record, and run snapshot. When the intermediate node has no persistent output, empty output cannot alone prove that the node is not running.

The response fields are as follows.
