Using a custom backend

You can provide a custom backend to be used. This backend has simply to implement the interface ISessionBackend

class ISessionBackend(ABC):
    @abstractmethod
    async def get(self, key: str) -> Optional[dict]:
        raise NotImplementedError()

    @abstractmethod
    async def set(self, key: str, value: dict, exp_in_mins: str) -> Optional[str]:
        raise NotImplementedError()

    @abstractmethod
    async def delete(key: str) -> Any:
        raise NotImplementedError()
