ben-manes/caffeine

Caffeine is a high-performance, concurrent caching library for Java that provides in-memory cache implementations with support for expiration, size/weight limits, and asynchronous operations. The system includes a comprehensive simulator for evaluating cache replacement policies and a JCache (JSR-107) adapter for standard compliance. It also offers a compatibility layer for the Guava Cache API and tools for performance benchmarking and static analysis.

This period focused on expanding the library's API surface with asynchronous cache operations and a complete JCache (JSR-107) implementation, including management beans and event handling. Concurrently, the cache simulator was significantly enhanced with new replacement policies, admission frameworks, and trace parsing capabilities to support advanced cache algorithm research.

This period focused on significantly expanding the cache simulator's capabilities by adding numerous trace file parsers, new cache policies, and adaptive tuning algorithms. The project also standardized build configurations and added several usage examples, including support for Java modules and GraalVM native images.

50 changes

This period focused on modernizing the build system with automated JVM provisioning and enhanced IDE integration, while significantly expanding test coverage. The team added extensive concurrency, JMH, and OSGi tests, alongside new features like an indexable cache example and SNIA trace support.
