Sync (link):
header_params = {}
if request.project_id:
header_params["project_id"] = request.project_id
if request.database_id:
header_params["database_id"] = request.database_id
if header_params:
metadata = tuple(metadata) + (
gapic_v1.routing_header.to_grpc_metadata(header_params),
)
Async (link):
metadata = tuple(metadata) + (
gapic_v1.routing_header.to_grpc_metadata(
