public static final class LineageGrpc.LineageBlockingStub extends AbstractBlockingStub<LineageGrpc.LineageBlockingStub>

A stub to allow clients to do limited synchronous rpc calls to service Lineage.

Lineage is used to track data flows between assets over time. You can create LineageEvents to record lineage between multiple sources and a single target, for example, when table data is based on data from multiple tables.

Methods

batchSearchLinkProcesses(BatchSearchLinkProcessesRequest request)

public BatchSearchLinkProcessesResponse batchSearchLinkProcesses(BatchSearchLinkProcessesRequest request)

Retrieve information about LineageProcesses associated with specific links. LineageProcesses are transformation pipelines that result in data flowing from source to target assets. Links between assets represent this operation. If you have specific link names, you can use this method to verify which LineageProcesses contribute to creating those links. See the SearchLinks method for more information on how to retrieve link name. You can retrieve the LineageProcess information in every project where you have the datalineage.events.get permission. The project provided in the URL is used for Billing and Quota.

searchLineageStreaming(SearchLineageStreamingRequest request)

public Iterator<SearchLineageStreamingResponse> searchLineageStreaming(SearchLineageStreamingRequest request)

Retrieves a streaming response of lineage links connected to the requested assets by performing a breadth-first search in the given direction. Links represent the data flow between source (upstream) and target (downstream) assets in transformation pipelines. Links are stored in the same project as the Lineage Events that create them. This method retrieves links from all valid locations provided in the request. This method supports Column-Level Lineage (CLL) along with wildcard support to retrieve all CLL for an Entity FQN. Following permissions are required to retrieve links:

• datalineage.events.get permission for the project where the link is stored for entity-level lineage.
• datalineage.events.getFields permission for the project where the link is stored for column-level lineage. This method also returns processes that created the links if explicitly requested by setting max_process_per_link is non-zero and full process details are requested via links.processes.process in the FieldMask. Permission required to retrieve processes:
• datalineage.processes.get permission for the project where the process is stored.

Parameter
Name	Description
request	SearchLineageStreamingRequest

Returns
Type	Description
Iterator<SearchLineageStreamingResponse>

searchLinks(SearchLinksRequest request)
