Product Decisions This Supports

Enables building high-performance, non-blocking applications where cache operations must not stall the event loop (e.g., real-time APIs, WebSocket servers, or microservices handling concurrent connections)
Provides a standardized PSR-16-inspired interface to decouple cache logic from implementation, allowing seamless swaps between in-memory (ArrayCache) or distributed cache adapters (e.g., Redis) without rewriting core business logic
Reduces technical debt by avoiding custom cache implementations—critical for async ReactPHP ecosystems where synchronous cache calls would cripple scalability
Supports critical patterns like "fallback get" and "fallback-get-and-set" for seamless cache-miss recovery while maintaining non-blocking behavior during data source fetches

When to Consider This Package

✅ When building ReactPHP-based applications requiring async cache operations (e.g., event-driven servers, real-time systems, or I/O-heavy services)
✅ When needing a lightweight, interface-first cache abstraction that aligns with ReactPHP’s async philosophy
✅ For projects where cache operations must never block the event loop (e.g., high-concurrency HTTP servers or WebSocket applications)
❌ When using traditional synchronous PHP frameworks (Laravel, Symfony, etc.) without ReactPHP integration—synchronous cache solutions like Symfony Cache or Laravel Cache would be more appropriate
❌ If distributed caching (Redis, Memcached) is required out-of-the-box; this package only defines the interface and requires separate adapter packages (e.g., `reactphp/
