Caffeine cache¶

Caffeine is a high-performance caching library for Java. It is designed to be an optimal replacement for the Guava caching library, offering significantly improved throughput and better handling of concurrent loads^[600-developer__principle__cache.md].

Performance and Design¶

Caffeine is often described as the fastest Java caching library due to its sophisticated design choices. It uses an optimized window TinyLFU eviction algorithm to identify frequently used items efficiently^[600-developer__principle__cache.md]. The library constructs high-concurrency data structures that minimize write contention, allowing it to outperform alternatives when dealing with high volumes of data requests^[600-developer__principle__cache.md].

Usage Contexts¶

• Spring Boot Integration: Caffeine is commonly used in Spring Boot applications as part of a Multi-level caching architecture^[600-developer__principle__cache.md].
• Multi-level Caching: It is frequently paired with distributed caches like Redis; Caffeine typically serves as a local first-level cache (L1) to handle high-speed requests, while Redis acts as a second-level cache (L2) for shared data persistence^[600-developer__principle__cache.md].
