Description: _to_grpc_metadata is used to convert a tuple of string metadata into the proper GCP routing format. It is part of the hot-path of rpcs with routing info, and it adds a noticable cost to each rpc. But typically, the same values will be used for each rpc This PR adds a functools.lru_cache wrapper, to memoize the most recent paramaters used import timeit import functools from google.api_core.gapic_v1.routing_header import to_grpc_metadata metadata = (("table_name", "projects/p/tables/my-table"),) result = timeit.timeit(lambda: to_grpc_metadata(metadata)) print(f"orig time: {result:0.2f}") cached_to_metadata = functools.lru_cache(to_grpc_metadata) result = timeit.timeit(lambda: cached_to_metadata(metadata)) print(f"cached time: {result:0.2f}") orig time: 1.19 cached time: 0.07
