event. For streaming scenarios, it should be the end of the period from
which the lineage is being reported.
Immutable. The resource name of the lineage event.
Format:
projects/{project}/locations/{location}/processes/{process}/runs/{run}/lineageEvents/{lineage_event}.
Can be specified or auto-assigned.
{lineage_event} must be not longer than 200 characters and only
contain characters in a set: a-zA-Z0-9_-:.
Required. The beginning of the transformation which resulted in this
lineage event. For streaming scenarios, it should be the beginning of the
period from which the lineage is being reported.
