This class has three public methods to manage the cache:

  • set(name, value) this function set a new cache value or replace the previous.

  • get(name) this function return the cache element if it is stores, otherwise it will return a None value.

  • set_connection(RedisConnection) this function allows you to set the redis instance to be used.

from lru_redis_cache import LRUCache

cache = LRUCache(cache_size=5, ttl=60)

cache.set("my_key", "my_value")
cache.get("my_key")

# Output
"my_value"
