Redis-py contains two Parser classes: PythonParser and HiredisParser. By default, if the hiredis module is installed, redis-py will use HiredisParser; otherwise, PythonParser will be used. HiredisParser is written in C and maintained by the redis core team. Its performance is more than 10 times higher than that of PythonParser. Therefore, it is recommended to use HiredisParser.
