When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place. chunk_size must be of type int or None. A value of None will function differently depending on the value of `stream`. stream=True will read data as it arrives in whatever size the chunks are received. If stream=False, data is returned as a single chunk.
