flushdb and flushall after clear

[Martenz]

Would it be possible to flush also the db and or all when clearing a specific namespace or the entire cache?
It seems keys are removed but space is still used in redis db after calling the clear method.

Thanks.

I made this temporary extent of the backend class to have it done. I guess it can be included in the backend methods. Not sure this is the best way to do it.

class RedisBackendFlush(RedisBackend):
    def __init__(self, redis: Union["Redis[bytes]", "RedisCluster[bytes]"]):
        super().__init__(redis)

    async def flushall(self):
        return await self.redis.flushall()
