## Description

JetCache is a Java caching framework that provides a unified interface for managing application data. It functions as a two-level cache manager, coordinating local in-memory storage and remote distributed caches to reduce network latency and improve retrieval speeds.

The project is distinguished by its declarative caching library, which uses annotations to automate the storage, expiration, and invalidation of method results. It includes a distributed cache synchronizer to maintain consistency by invalidating local entries across cluster instances and a distributed locking tool to coordinate access to shared resources.

The framework covers a broad range of performance and stability capabilities, including non-blocking asynchronous retrieval, automatic background cache refreshing, and request collapsing to prevent cache penetration. It also provides programmatic cache management, pluggable serialization strategies, and security features such as allow-list deserialization filtering.
