class Encoder:

Feature request: Make Encoder configurable to allow users customize the transformation of keys and values.

• namespacing (key prefix)
• different encode/decode algorithm
• encode/decode user-defined types, like dict or numpy.ndarray

class MyEncoder(Encoder):
  ...

client = Redis(host=..., encoder=MyEncoder())

We currently manually serialize non-bytes to bytes outside redis-py, and only pass bytes to redis-py.

    def encode(self, value) -> Union[bytes, memoryview]:
        if isinstance(value, (bytes, memoryview)):
            return value
        elif isinstance(value, (int, float)):
            value = repr(value).encode()
        ...
        return value

Without customizable Encoder, it's difficult to switch between redis libraries.
