Caching Service Implementation

An in-memory caching service with LRU eviction and database synchronization for efficient data retrieval.

FEATURES:

• Set max cache size during initialization.
• Automatically evicts the least recently used (LRU) items when the cache exceeds the size limit.
• Fetches from cache first; if not found, retrieves from the database.
• Clears cache without affecting the database.
• Evicted data is persisted to the database.
• The Entity class has a unique identifier, accessible via the getId() method, which returns the unique ID of the object.
• Logs all actions (add, remove, eviction, retrieval) for transparency and debugging.
• Follows industry-standard exception handling practices to ensure robustness and stability.

METHODS SUPPORTED:

• add(Entity e1): Adds entity, evicts LRU if needed.
• remove(Entity e1): Removes entity from both the cache and database.
• removeAll(): Clears all entities from both the cache and database.
• get(Entity e1): Retrieves entity from cache or database.
• clear(): Clears the cache only.
