The code iterates through the data list twice. First to calculate combined_size and then to create the chunks. This could be combined into a single loop for better efficiency. Consider calculating the combined_size while creating the chunks, and only yielding the combined data if it's within the limit. If it exceeds the limit, yield the accumulated chunks and start a new chunk.

            current_chunk = []
            current_chunk_size = 0
            for chunk in data:
                if current_chunk_size + len(chunk) <= MAX_STREAMING_CHUNK:
                    current_chunk.append(chunk)
                    current_chunk_size += len(chunk)
                else:
                    if current_chunk:
                        yield b''.join(current_chunk)
                    current_chunk = [chunk]
                    current_chunk_size = len(chunk)
            if current_chunk:
                yield b''.join(current_chunk)
