def redis_cache():
    return caches.get(CACHE_KEY)


@app.get("/")
async def hello(cache: RedisCacheBackend = Depends(redis_cache)):
    in_cache = await cache.get("some_cached_key")
    if not in_cache:
        await cache.set("some_cached_key", "new_value", 5)

    return {"response": in_cache or "default"}
