CACHE_CONFIG = {
    "CACHE_TYPE": "minio_cache.MinioCacheBackend",
    "CACHE_MINIO_ENDPOINT": "localhost:9000",
    "CACHE_MINIO_ACCESS_KEY": "minioadmin",
    "CACHE_MINIO_SECRET_KEY": "minioadmin",
    "CACHE_MINIO_BUCKET": "superset",
    "CACHE_MINIO_SECURE": False  # Set to True for HTTPS,
    "CACHE_DEFAULT_TIMEOUT": 300,
