If you can chunk the response json-seq/xml (sax parser) may be worth looking at. The server can incrementally stream a chunk and client incrementally consume a chunk keeping flat memory usage. I think gRpc also supports streaming but don’t know much on it. JSON is a bad format for large files as generally you need to read the entire file in to memory before you can use it as you observed.
