Class LineageGrpc.LineageStub (0.34.0)

public static final class LineageGrpc.LineageStub extends AbstractAsyncStub<LineageGrpc.LineageStub>

A stub to allow clients to do asynchronous 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, StreamObserver<BatchSearchLinkProcessesResponse> responseObserver)

public void batchSearchLinkProcesses(BatchSearchLinkProcessesRequest request, StreamObserver<BatchSearchLinkProcessesResponse> responseObserver)

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.

Parameters
Name	Description
`request`	`BatchSearchLinkProcessesRequest`
`responseObserver`	`io.grpc.stub.StreamObserver<BatchSearchLinkProcessesResponse>`
