Storage types

• TEXT
• JSON
• BINARY
• PICKLE

Core methods

• get(key, ttl=None)
• set_text, set_json, set_binary, set_pickle
• exists(key)

Decorator usage

import datetime
from naas_abi_core.services.cache.CachePort import DataType
 
@cache_service(
    key_builder=lambda user_id: f"user:{user_id}",
    cache_type=DataType.JSON,
    ttl=datetime.timedelta(hours=1),
)
def load_user(user_id: str):
    return {"id": user_id}

To force bypass:

load_user("123", force_cache_refresh=True)

Adapter

Current built-in adapter: filesystem (CacheFSAdapter) via CacheFactory.CacheFS_find_storage(...).
