Cache Service

CacheService provides typed cache storage plus a decorator for function-level caching.

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}
```bash

To force bypass:

```python
load_user("123", force_cache_refresh=True)

Adapter​

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