You could try using the redis HSET command to store the dict as a redis hash with something like for k, v in my_dict. Time complexity: O(1) for each field/value pair added, so O(N) to add N field/value pairs when the command is called with multiple field/value pairs. To avoid blocking behavior the commands SCAN and HSCAN can be used which allow only a small number of elements to be retrieved on each call.
