Methods

BatchSearchLinkProcesses(BatchSearchLinkProcessesRequest, ServerCallContext)

public virtual Task<BatchSearchLinkProcessesResponse> BatchSearchLinkProcesses(BatchSearchLinkProcessesRequest request, ServerCallContext context)

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][google.cloud.datacatalog.lineage.v1.Lineage.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.
